    This exhaust not only sounds great but it also looks fantastic. It provides a great snarl under acceleration

    Corsa is the best brand out there when it comes to aftermarket exhaust systems. I’ve had it on several cars and trucks in the past and I will not use anything else. It bolted up very easily and it sounds really good! The Xtreme is louder than the Sport, so be prepared for it to be louder than most exhaust systems. If you buy this system, you will absolutely love it!
