you might not see much in the way of bhp, maybe 2-3bhp

however you will notice a difference in the way the car drives, my car became more responsive, with more mid range.

i would only recommend one though if you have all the other basic tuning mods - manifold, goot cat back, good induction.

hardly worth it mate, will only ave to put it back on for m.o.t. + police do random stops these days and do emission tests...not worth the hassle imo, will gain like 1-3bhp if that!!

as said its a mod to do as an addition to other mods, if ya fine about swapping the cat back at mot time then do it, i must admit its next on my list but its one of the ast things to do. I have been told ya lose low down tourqe though

i lost nothing with the addition of mine.
