I am still CBE searching and ya...still know it isn't a giant gain. I will do the DP and MP later on when the car has more miles and I have decided to keep it for 5 years or just a few. I like the price of the corksport to be honest but have no idea what it sounds like by itslef. I could only find clips of the entire TBE. Right now I am 90% on a TurboXS cat back. Just need to hear or be told the corksport is better or worse or what ever.........
