This downpipes nowadays have been shown to increase horsepower. An aftermarket downpipe with catalytic converters will add 10 to 20 horsepower on average, and that gain is noticeable anytime the turbo spools.2. Downpipes certainly will make a car louder with a more aggressive exhaust note. Flashark ones are louder than stock because they reduce the backpressure that occurs in restrictive exhaust pipes.3.

Racing cars and speed boats usually use this product to save weight. With a high-performance exhaust system, we’re talking about even more weight savings. If you want the most power out of your engine and you don’t care about additional noise in your neighborhood, test pipes are the best way forward. If you want your test pipe to have the most volume and the most aggressive sound, you should stick with a straight line.

All of the hydrogen and carbon in gasoline would entirely burn out and transform into carbon dioxide and water in an ideal, frictionless engine. Since this is not the case, cats are the only way to go when designing exhaust systems. The catalytic converter is the most limiting part of your exhaust system, as you undoubtedly already know. Although a test pipe is not something we advise doing, especially for daily driving, you can think about it if you want to get the most out of your exhaust system.

Charge pipes are called so because they add an additional charge to your exhaust system. Charge refers to the air inside your cylinder, and since charge pipes direct air toward the turbocharger, the overall air inside cylinders increases significantly as a result of turbo spool. Read our guide on exhaust headers vs exhaust manifolds for a better understanding. All of our products come with all the necessary bolts and gaskets to make installation simple and straight forward. Nissan 370Z 09-up, 350Z 07-08, Infiniti G37 08-up, G35 Sedan 07-up.

These pipes completely remove your factory catalytic converters and replaces them with a straight through design. This provides the absolute most flow possible which has shown gains on NA 350zs between 4-8HP making it one of the best “bang for the buck” mods. They have also tended to add a “raspy” exhaust note through the 3-4k range. This note has been loved by some, and hated by others, so it is not for the conservative.

These test pipes are expertly designed to improve exhaust flow, delivering more power while maintaining a refined and balanced exhaust note. Crafted from top-quality materials, they are built to last, and their bolt-on installation makes the upgrade process hassle-free. For those seeking a performance boost and a pleasing exhaust sound, these resonated test pipes from Fast Intentions are the ideal choice to elevate your driving experience.

You won’t need to move the studs, but you will need to run DE test pipes or cats. Yes, you will just need to run them with DE test pipes or cats. He is a true motorhead at heart and loves writing, especially about engines and vehicular dynamics. No, as we mentioned earlier, test pipes and downpipes are different, downpipes come before test pipes, and they connect to the exhaust manifold.

We will send you a replacement part and provide you with a prepaid return label to return the defective part. In some instances, return of the product may not be required. If the damage was caused by a shipping courier, we will schedule a damage pick up by the courier.

A test pipe with a resonator or a small muffler is ideal for a deeper and more muted tone. Exhaust tone and loudness may be lowered by using these devices, which can also provide a deeper sound in some instances. The amount of exhaust produced when the catalytic converter is removed is significantly increased. This reduces back pressure and improves turbine flow in automobiles equipped with turbochargers. Another solution that we will be focusing on later in this article is installing high-flow catalytic converters, but for now, let’s see whether test pipes improve performance figures.

Exhaust pipes that are too restrictive must be removed if you want to get the maximum performance out of your engine. A catalytic converter has a different air-flow design, and hence, has different pressure values, which you’ve changed when you install a test pipe. Elevate your vehicle’s exhaust system with this 2-piece 3-1 stainless steel Test Pipes, ensuring a surge in engine performance, increased horsepower, and an exhilarating driving experience. Don’t miss out on this opportunity to boost your ride’s power and style with a product that’s built to meet or exceed OEM standards. Normal downpipes have a catalytic converter that cleans the exhaust gases as they are produced. But these catalytic converters cause you to lose power as it has a restrictive aspect of cleaning the exhaust gases.

The aftermarket performance part replacement for the catalytic converter for Nissan and Infiniti cars. YPerfomance’s auto engineers designed, developed, and tested this custom test pipe for the past years and got the best result for the perfect performance for Nissan and Infinity cars. Megan Racing Stainless Steel Down-pipes are made of the same high-quality T-304 that is utilized in our Headers and Turbo Manifolds for extreme durability and resistance to corrosion and cracking. The missing component between any Header/Manifold and your Cat-Back system, these Down-pipes will complete the high-flow exhaust system desired for the performance of your vehicle. With a noticeable power gain throughout the rev-range and a polished finish, these are a perfect addition for any performance vehicle.

Currently, only 50% of the thermal energy produced by an engine when a gallon of gasoline is used is transformed into mechanical force. If 50% sounds inadequate, keep in mind that the majority of cars on the road, especially the older ones, expel over 80% of their thermal energy through the exhaust. One solution is to keep the original cat with you at your house.

Test pipes are pretty much illegal everywhere, as well within the USA. See, every engine uses motor oil, and often at times, motor oil gets combusted along with fuel. This produces toxic exhaust gases, that are rich in pollutants, so a catalytic converter must be used to filter these out. The catalytic converter has a honeycomb mesh inside it that causes a big hindrance in the exhaust flow. Replace it with a straight pipe, and you have your test pipe all set up. The resonated test pipes are constructed using high quality stainless steel.

We use premium quality stainless steel to produce our product and upgrade the flex pipe with our new design which will efficiently bring down the engine temperature. I ordered my test pipes thinking they where gonna arrive in a couple months but I only waited 2 weeks! And the customer service is awesome and the best thing is the free shipping. My test pipes where a great addition to my z and so far no check engine light. Tuning the sound of an exhaust system adds an additional layer of complexity to the performance aspect of the design process. The goal is to design a system that sounds great, without adversely affecting performance.

This product is intended for off-road/competition use, and may not be legal for use on highway or street vehicles in your area. Some products sold by Concept Z Performance may solely be used on vehicles in sanctioned competition, which may never be used upon a public road or highway, unless permitted by specific regulator exemptions (such as CARB E.O.). Although they are slightly more expensive than test pipes without resonance, they still give you a smooth exhaust flow. Expect modest increases in horsepower and torque and an increased average. Installing high-flow catalytic converters or resonant test pipes are two other potential choices to improve the sound of your exhaust, in addition to increasing the flow of your exhaust.

This also acts as a check and balance for the throttle and fuel system, and if the sensor picks up different O2 concentrations than what’s normal, a check engine light will most likely appear on the dash. If a lot of oxygen is present, little fuel is being injected, and the O2 sensor sends a signal to the ECU to correct this. If there is little to no oxygen present in the burn mixture, the sensor sends a different signal to the ECU, which opens the throttle body more to allow more air to flow inside the engine. You can manufacture a test pipe using basic power hardware like a band saw, and precision TIG welding equipment. The relatively low cost of making a test pipe also makes it more appealing to tuners, looking to maximize their power output on a low budget. Test pipes are also often used for both race and off-road use, mainly because temperatures in both of these setups exceed regular values, and thus, a test pipe is preferred.

Correct, to run these on an HR or VHR, you would need to pair them with DE test pipes. These would require DE test pipes to fit, so they would not work with your current G37 test pipes. Hi Daniel, the only other way would be to cut the flange off your test pipes and weld on DE flanges.

Just keep in mind that one of them, resonating test pipes, is still an unlawful change. On the other hand, high-flow cats are permitted to use on public streets. The principal function of a catalytic converter also referred to as a “cat” or “cat-con,” is to transform dangerous exhaust pollutants into less-toxic gases before they are released into the atmosphere.

In turn, this impact will reduce backpressure and decrease turbine speed within the turbocharger, impairing overall power output. The exhaust gases travel through a ceramic honeycomb structure inside the catalytic converter that is made up of thousands of tiny ducts. Every car must come equipped with a catalytic converter by law, and depending on where you reside, it may be quite unlawful to remove this part from your exhaust system. This is mostly because turbos rely a lot on exhaust pressure, so it’s easy to see why improving the exhaust flow on a turbo engine responds much better to a test pipe configuration. Your turbo might end up making more boost, which can be both bad or good, depending on your engine internals, and other components. Test pipes are also sometimes confused with charged pipes, but the two are quite different from each other.

Keep in mind that engines are spinning at thousands of RPMs. Exhaust gases are being produced at the same rate, and for this, engines need a good exhaust route as much as they need fuel and air. Talk to any engineer and he or she will tell you that getting air in and out of an engine is always a big problem. The 28th Scheid Diesel Extravaganza is held on August 23-24, 2024 at Wagler Motorsports Park in Lyons, IN. AFe POWER will be attending as a vendor and look forward to meeting everyone there with new exciting products to show for all your diesel needs and wants. Torque increases, this TAKEDA Momentum Intake is just what the Subaru WRX has been waiting for.

The other 4% is much less then what is needed to cover all other costs and expenses lost by cancelling an order, that was already processed. This fee is will only be imposed on orders that have not shipped. If a special order has been placed, such as pistons, turbo’s, etc., and the items are built and ready to ship out, and a cancellation is requested, a 25% cancellation fee will be imposed IF possible to be cancelled. 1320 Performance Stainless steel cats are made from high-quality SUS-304 that is utilized in our header that is 1.5mm thick for extreme durability and resistance to corrosion and cracking. Hi Daniel, the only difference is the flanges where the headers meet the test pipe. So you would need to swap the flanges on your test pipes for DE flanges.

Free shipping items will have the initial freight fees deducted from the final refund. This information will be revealed to you up front upon requesting a return. Once the refund has been issued a confirmation email will be sent.

Buyer assumes all risk of injury or loss which may result from using this product in a manner for which it is not intended. Far more engineering goes in to the design of an exhaust system than many realise. From a performance perspective, there is a fine balance between exhaust back pressure and exhaust gas velocity. There are many other technical aspects such as “scavenging effect” which are beyond the scope of this document, but the point is, it’s not as simple as just strap on a drain pipe and gains for days. A “quality” exhaust system maximizes performance gains by design.

A free-flowing exhaust is just as crucial as an unrestricted air intake for your engine to operate at its best – this is where test pipes prove their worth. The aFe POWER D.A.S. PLUS induction system combines a Dynamic Air Scoop (D.A.S.) and a high-performance aFe POWER drop-in Pro DRY S filter. Together, they work seamlessly to enhance the efficiency of your factory airbox by maximizing the flow of cool ambient air throughout the system. The aFe POWER D.A.S. PLUS Induction system for Ford F-150 combines a Dynamic Air Scoop (D.A.S.) and a high-performance aFe POWER drop-in Pro DRY S filter.

Disclaimer In effort to provide our valued clients with the most up to date and accurate information, JM Auto Racing is continuously implementing real-time updates to our online superstore.

These resonated test pipes utilize stock flange locations so they can be used with stock components or aftermarket (Provided they aftermarket components use stock style flanges and mounting locations). Our customers are delighted with the catless test pipe 370z system which gave an improvement in exhaust flow and horsepower. A catless downpipe doesn’t have a catalytic converter inside, thus it doesn’t restrict the flow of exhaust gases nor does it clean it. Hence the flow of exhaust gases through a catless downpipe will be free flow and significantly higher than that of the catted downpipe. To withstand the high temperatures laser cut cast steel flanges are used to ensure long lasting leak free reliability.

First, a 3D scan is take of the underside of the car to ensure fitment is 100% correct. Next, grade 304 Stainless Steel (with the exception of their titanium systems of course) is selected for all piping, mufflers and flanges. This particular grade is chosen for its strength, durability (ability to withstand the elements),and its ability to be formed and welded with relative consistency and ease. Cast flanges are then used which ensures 100% correct fitment every time, no leaks or additional stress points, and long lasting strength. The Berk Technology facility houses a state-of-the-art research & development center where extensive testing goes into each and every one of their products.

A noise ordinance establishes the types of noise that are and are not permitted at any given moment. I would therefore check with the local authorities to see what the laws are where you live. For additional information on mufflers and resonators and what they’re doing in your exhaust system, read this guide.

It is not uncommon to develop drone and rasp while freeing up the exhaust flow of your vehicle. The factory catalytic converters leave a lot of power on the table with their smaller piping and extremely dense core. While being a very simple and inexpensive bolt-on modification, upgrading to aftermarket test pipes is a no-brainer. AAM Competition Resonated Test Pipes replace the factory catalytic converters and are designed purely for off-road performance. Our test pipes are the premier upgrade for all Nissan/Infiniti owners looking to maximize power and performance from their VQHR V6 engine.

If you own a 350z, check out these aftermarket test pipes for your car. We also have different options for the 370z, in case you’re interested. The more unrestricted your intake is the more smoothly you can get air in, and the more unrestricted your exhaust is; the smoother air exits the engine. Read our example on different air intakes for your 350z, to understand this better. LUXMA Exhaust Downpipes are made from a very experienced manufacturer who makes products for many named brands in United States and Europe. We provide a 60-day return policy; for detailed information, kindly refer to our return policy section.

This metallic mesh is coated with rare metals like platinum, palladium, and rhodium. This mesh is what actually cleans up exhaust gases, and since high-flow cats preserve this methodology, they are still viable to install in any road-legal car. Although high-flowing cats are virtually identical to standard catalytic converters, they are made to conserve power while still producing clean emissions. Depending on whether you value horsepower or environmental sustainability more, catalytic converters are either the greatest or the least critical part of your exhaust system.

Resonated test pipes are identical to standard test pipes, with the exception that a Helmholtz resonator is fastened to them. With less drone than non-resonated test pipes, they flow better than the stock cat-con and high-flow cats. Catalytic convertors are also necessary due to internal combustion engines’ ridiculously low efficiency.

Our resonated test pipes are the premier upgrade for all Nissan/Infiniti owners looking to maximize power and performance from their VQHR V6 engine. We maximize performance by eliminating your OEM catalytic converters, increasing the tubing diameter, and adding straight through perforated core resonators to free up back pressure. The factory exhaust will always have restrictions and these restrictions are normally highest near where the catalytic converter is found. Invidia Exhausts use a larger pipe diameter and smooth bends which allows exhaust gases to pass with fewer restrictions and turbulence. A High-Flow catalytic converter is then utilised to still control emissions for street driving legalities but with minimal impact to exhaust flow. In some cases Invidia will also offer catless versions for off-road use where every ounce of performance is required.

If you have a nice pair of test pipes and a tune, you’ll witness a gain of over 10whp, 5w, and sharper throttle response, as well as a quicker needle, rise in the rpm range. Catalytic converters made by the original equipment manufacturer (OEM) are likewise prone to failure and need expensive replacement. That issue can be solved at a reasonable cost by using test pipes. Test pipes have grown in popularity among automobile enthusiasts because they are a low-cost, high-impact alteration. No, you will need to switch to DE test pipes to run these headers.

If you’re looking for unbridled horsepower, modifying your standard exhaust system might be a good option. A test pipe is just a straight pipe that replaces your catalytic converter. Because of these reasons, Invidia front pipes and cat pipes make for the most popular exhaust upgrade that adds a substantial bump in both horsepower and torque. Refunds for returned products are issued with 3-5 business days once they are received by our warehouse and inspected. Refunds will be issued via the same payment method originally used to place the order (Credit Card, PayPal, Google, Affirm, Check). All returns, where JM Auto Racing is not at fault, will have 15% restocking fee less than cost of freight.

An ECU tune will correct this, and after this is sorted out, you will see higher power figures. A turbo engine will require an ECU tune more than a N/A engine since the turbo is also connected to ECU, which controls how much it spins and compresses air. All of this has to do with stock pressure values for any engine. Now cats can go bad because your engine’s exhaust gas temperature is high, which translates to potential corrosion. Replacing the cat is going to be pretty costly, and one cheap fix is installing a test pipe, which you can do at home.

Let’s go over these resonated test pipes in greater depth. Regulatory bodies are set up everywhere that monitors emissions from exhausts for this exact reason. A test pipe will also improve torque figures, and you’re going to see the RPM jump up faster when you press down on the gas.

Your engine’s ability to produce additional power is entirely dependent on airflow. The intake and exhaust systems are therefore frequently modified first. Well, when you’re fitting a straight pipe in place of the cat, you’re messing with the burn ratio. When you fit a test pipe, you lower the pressure in your exhaust, and this fools the engine into thinking that it needs to work harder to maintain that pressure.

While some jurisdictions that don’t monitor for emissions make it easier to get away with test pipes, others have rigorous laws and severe penalties. This nifty bit of engineering is actually what supercar and hypercar manufacturers use. A good example is Koenigsegg, which uses high-flowing cats in the exhaust system in every car they manufacture. Coming back to power figures, a test pipe is capable of increasing power output by a maximum of 10 if the engine has gone through an ECU tune also. For turbo engines, however, a test pipe setup will increase power figures by at the dyno.

For Nissan 350Z and 370Z owners with the VQHR engine, the Fast Intentions VQHR FI Resonated Test Pipes offer a balanced approach to performance and sound enhancement.
