I was thinking of something like the Baily EvoR twin piston. Tried a friends on my car, sounded the dogs. Any thoughts? Do any of you have these fitted? I was told by the guys at Well Lane that it shouldn't cause any problems.

244bhp @ 6120 rpm 220lb/ft

 

I have one on mine and haven't had any probs, sounds good but goes off constantly, even on lightish throttle (not that that bothers me). A mate has a HKS super sequential which sounds even better but cost about £270 !

 

Lot of money to spend to get some noise.
It will not increase power.
Unless the standard is leaking or you badly want the noise spend the money on something more useful. IMHO
