Test Pipes are primarily used in place of catalytic converters and are designed to completely eliminate catalytic converters to reduce exhaust drag and increase power output, typically used in track and high performance applications.

For the 2008-2018 Nissan 370Z and Infiniti G37, test pipes eliminate the restrictive catalytic converters, allowing for a more free-flowing exhaust. This modification can lead to significant gains in horsepower and torque, enhancing the overall performance of these engines. Without catalytic converters, there's less concern about clogging or failure of these components, leading to potentially lower maintenance costs over time.

1. Do downpipes add horsepower?
Yes. 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. Will a downpipe make my car louder?
Yes. 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. Will a downpipe void my warranty?
No worries. Installing an aftermarket downpipe doesn't void your vehicle's entire warranty. If you are a United States resident, then you're protected by the Magnuson Moss Warranty Act.

Good for the Price and NO CEL

these are pretty much worth it, only downside is the gaskets. I bought thick gaskets from CZP and put ultra copper and it fixed my horrible exhaust leak but overall it’s worth it

Thank you for your feedback, we will inform the developers and continue to improve our product.

370z Test Pipes

These have been installed for a week. They are good quality and fit perfectly. I am very happy with the sound also. I am using these with my stock Nismo (test pipe/cat back) system. Gave the car some room to breath and still sounds stock ( no trumpets).

Thank you for your comment and I look forward to receiving your feedback pictures!
