Hi this is my first post so go easy
I'm thinking of building abit of a custom exhaust system, I was going to go for a ebay special decat down pipe, a milltek resonated centre section then just have a pipe coming off it out to r32 style tips, opinions and criticisms welcome
I just wanted to know mainly about the back box is it goin to be stupidly loud and droney without one?
If anyone else has done something like this before you advise would be fantastic
