All I got is the standard bore pipe (2" I think) headers and three coby's all about 15" long. The car has made 120rwkw on the dyno with this set up, how ever she only ran 108rwkw the other day :confused:
Anywho, I think the important thing is to avoid using stainless anything on the system as this resonates badly with the N/A's.
Also, a turn-down or dump pipe at the end will keep the bark away too.
I get many comments on how good it sounds yay!
