Nice numbers if you just get with catback itself 26hp, but remap no need for just catback, akrapovic sais their catback gets 7kw extra (about 10 hp) http://imageshack.com/a/img922/8392/l7523T.jpg
So only with catback and downpipes you can get nearly 70 hp plus you do remap 80 hp in total 150 hp not bad
