Get to MotorMech . I'm off on Saturday for custom duplex system fitted. So actually...I can't yet comment on whether they are any good, but there have only been good things said about Paul and the team on here!
I use to have a supersprint on my old 20VT and I think it looks one of the best out of all of them, quetish, and then when you put your foot down its a sporty raspy sound, lovely!
At the min, I have a custom made Longlife, very good quality but expensive. You tell them what you want and hey presto....
Out of interest, what kind of difference power wise would find with complete turbo back and larger down pipe as to a cat back? I think i've read somewhere on the forum before that it helps increase with fuelling or did I just make that up?!
For quite and racy sound Super Sprint all the way. Looks the best too. Since moisture is minimal in the middle east it lasts life long.....i read some topics in the forum that they begin to rust in the UK after 3 years.
