 ISR Performance Over Pipe, Test Pipe, and Street Cat-Back Exhaust


We are very pleased with the performance and sound. 

Compared to the HKS Exhausts which are over 1K - and made 0 HP gains on our car. We think the ISR Exhaust at $600 and 6hp is awesome bang for the buck setup.

    Bought this exhaust looking for something not too crazy loud and affordable. Also the horsepower gains were good compared to all the other exhaust on the market and for half the price. Highly recommend this exhaust. A+++
