    The only exhaust kit you should ever buy!

    I love my corsa sport kit!! I’ve ran multiple exhaust systems throughout the years and by far corsa is the best! The no drone technology is amazing! Even with long tube headers and an aftermarket cam I can have a nice conversation or even talk on the phone! Very simple install and great step by step instructions.
