ISR Performance Stainless Steel Resonated Test Pipe - Nissan 370z Z34

4 Star Rating


ISR Performance Stainless Steel Resonated Test Pipe - Nissan 370z Z34


The ISR Performance resonated test pipes are constructed using high quality stainless steel. 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.)

These test pipes will eliminate your catalytic converter, and are designed for off-road use only. Utilizing a small resonator, the ISR Performance resonated test pipes will help cut some of the rasp of the exhaust note of your modified VQ while still providing much better exhaust gas flow than the OEM catalytic converter. These will help add the maximum amount of horsepower and torque to your VQ, especially when paired with the ISR Y-pipe and exhaust!

  1. Fitment is right sounds is okay

    Lots of hissing on deceleration! Slight rasp when wide open throttle but other than that the sound is good. People think the car is boosted because of the hiss but its not. Packaging was terrible and one pipe had a small dent in it. Hardware it came with is not the same 14mm bolts and nuts, complicating installation slightly. Cant really complain for this price though.
