I got the whole system done as a oner as the exhaust it came with was pumped when i got it. So as to whether just the cat-back made more noise i canna say but once the whole system bedded in it sounds nicer than my black zs imo. The de-cat did make a big difference on the black zed though

Had the green zed RR'd at 199bhp with those mods, the black one made 190bhp with the same mods
