i had mine decatted (mid) and had the resonators removed and x pipe added. its feels more responsive, revs easier and sound FANTASTIC.
its not too loud at tickover or normal driving but when you flatten it it sounds like a F1 !
My back box's (mufflers) are std.
so then does the F1 sound primarily come from removing the X pipe resonators, or primarily from replacing the rear mufflers? I would like to get the f1 sounding exhaust note, but dont want the car to be ridiculously loud.....
