Fitted my Corksport cat back system yesterday and am very happy with it. It has a really deep bass note and was easy to fit. The build quality of this exhaust is amazing! Its a shame it is under the car where you dont see it easily. I highly recommend this exhaust and was very impressed with how my purchase was packaged and shipped. Great service Corksport, thank you.
