330I back box or de cat?

essex_lad · 07-24-2013, 05:13 PM

So I am sending my 325I in for a remap with a 330I inlet manifold fitted to get me extra power. While it's in having a remap I can have a de cat or back box fitted. I don't want much more noise and mot isn't an issue what do you suggest?

Or do I just leave the msport exhaust it has as changing it won't make a blind bit of difference lol.

You mean take the cats out or have a muffler installed? Either one it'll make a lot more noise.

I take it the power increase wouldn't make up for the extra noise?
