Hi all, im just trying to get this clear in my head from somebody in the know, as i have had 2 comflicting views on it.

If i were to put in a straight through center section (removing the center cat), with an apropriate BB (assume they are both H&S), would it require a remap to be 100% safe or would it be ok to use in standard form? Surely i would have thought that the answer was no it wouldnt need a remap because the air flow sensors and whatnot would have already doen their job? Would the engine therefore be less stressed?

If someone can let me know the proper answer then it would be appreciated.

Cheers,

Neil.

ive got a de-catted centre and back box on mine, have had no problems at all, other ppl may know better than me but i dont recon u need a re-map for these mods.

Pete, what are you running? is it a classic?

yeah my97 uk classic

did you notice much power increase? smoother delivery? anything like that? Ive looked at the H&S center and rear and they suggest around 18bhp?

not really, its louder and the throttle is more responsive the car picks up a bit quicker but i dont think ive gained that sort of power!
