I think the exhaust is louder than advertise, and it vibrates the whole car. I also think the exhaust looks ugly hanging from the back, Corsa should've made an exhaust exactly like stock, and should've fit snug and smooth on the car instead of it hanging lower than stock and looking pretty ghetto. For only a axle back system, I am disappointed in the price, sound, and overall vibration of the car. Sounds like a Honda 4 cylinder instead of a Luxury Sports Car.
I expected a better fit
I have had several Corsa exhausts, and have never been disappointed until now. They sound great, but dual exhausts sit about an inch and a half too low, and it looks like the exhaust was an afterthought. I know the factory exhaust was perfectly situated on my CTS-V coupe rear end. That isn't the case with this unit.
