ISR Performance Stainless Steel Resonated Testpipe - Nissan 350z Z33 / G35 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! These are designed for 350z / G35's using the DE engine. These will not fit vehicles equipped with HR engines. Specs
