Cat-back exhaust system kits come standard with tailpipes, a performance muffler and exhaust tips. The inclusion of our wider, mandrel-bent tailpipes means cat-back exhausts are your go-to for increasing your performance gains along with boosting your sound. While horsepower and torque gains vary from vehicle to vehicle, you can expect anywhere from a percent gain in horsepower and torque after installing a cat-back exhaust system.
To make a very long story short so far so good I’m happy with the product. I had 1 dinged tip out of the 4 that prob happened during shipping n y’all already have a new replacement tip on the way so customer service is great as well. Only thing I would change as previously stated would be a little more noise but again that wasn’t my main goal to being with. Hats off to what y’all do and please make more B9 Audi S4 parts n I’ll happily buy them. I regret not buying the IE intake but hey sometimes we all make poor decisions lol. Every vehicle-specific CORSA product is engineered and designed to match the unique properties of the vehicle it is designed for to deliver perfect fitment and performance.
