I was looking to treat myself to the stainless steel janspeed competition manifold, cat back and sports cat for xmas and was wondering what sort of gains i would get from them also whats the difference in grp N or A?
Ive just read some posts and people have had a few problems with janspeed exhausts so is it worth going for a different make or was they unlucky?
