From the headers to the tip, they free up your exhaust system. 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. 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.
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. The resonated test pipes are constructed using high quality stainless steel.
Enhance your vehicle's performance with our expertly designed kit, crafted to deliver noticeable power gains and a refined driving experience. Whether you're looking to improve track times or simply upgrade your daily driver, this kit provides the quality and precision engineering you need to maximize your vehicle's potential. Trust RNJ Performance to provide the components that deliver both reliability and high performance, taking your vehicle to the next level. Both Test Pipes and Downpipes, like the FLASHARK G37 Test Pipes and 370Z Downpipe, are designed to increase horsepower. By improving exhaust flow and reducing restrictions, they can add 10 to 20 horsepower on average, with noticeable gains during high-performance driving. Even though they’re called test pipes, that isn’t what they do in a substantial way.
They’re only designed to replace the OEM catalytic converter to ensure maximum flow and performance. These straight pipes permit you to get more power out of your engine once the restrictive part is removed from your exhaust system. 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.
Most locations require that you have these converters installed in your vehicle for emissions control and safety reasons. Although high-flowing cats are virtually identical to standard catalytic converters, they are made to conserve power while still producing clean emissions. 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.
Their intake systems are designed to maximize airflow, ensuring your engine breathes better for improved performance and efficiency. For Nissan 350Z and 370Z owners with the VQHR engine, the Fast Intentions VQHR FI Resonated g37 test pipes Pipes offer a balanced approach to performance and sound enhancement. With their precision engineering, quality materials, and potential power gains, these test pipes provide a satisfying upgrade to your vehicle’s exhaust system. Elevate your driving experience with the Fast Intentions resonated test pipes and enjoy improved performance and a refined exhaust note. 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.
Our high flow catalytic converters will show almost equal gains, but straight throughs are a MUST for any FI application. To withstand the high temperatures laser cut cast steel flanges are used to ensure long lasting leak free reliability. This is a 100% bolt on installation for right-hand drive vehicles with no modifications or changes required. Factory O2 sensor locations are also retained where required to ensure compatibility with factory systems.
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. They use all factory mounting points and there is no modification to the vehicle.
