As I get older I'm getting tired of not being able to drive with my windows down because my exhaust is deafening. My current set up is Kooks LTH, Kooks X pipe, no cats and I'm not exactly sure about the cat back, I traded someone my Corsa extremes for what I believe is the Ford KR exhaust. What are some quieter options for a cat back without sacrificing HP/TQ? I always wanted the Borla Touring but I'm not even sure that will help. Thanks for any input or soundclips if you have any.
