Hey All,

I got a BA Ghia 3v, i have a 3" Single System, High Flow Metallic's and Pacies. Would there be any power benefit going for a twin 2.5" System thats mandrel bent.

Reason i ask is cuz alot of people with the same mods as me are making 15+KW more at the RW and i think the exhaust is causing the problem, but before i go blowing 900bucks on one i wanna know for sure.

Other mods are, BPT Tune, Cold Air Intake, Phenolic Spacers and 3.5" Pipe from airbox to throttle body. Got it dynoed and it makes 205.4RWKW.

Cheers in advance,

200rwkw is a good number!
IMO, a twin 2½" system would be a good fit for your current engine and still good for some more kw down the road.
Twins also have a different sound to singles.
Just slightly off topic a bit, I'd say the only time you would go for a twin 3" system would be if you are up at the 300rwkw mark.
