What a strange question, i'm struggling to make mine quiter, and i've already got 2 silencers..
Anyway:
Manifolds:
Cooper freeflow = deeper
LCb = throatier
Fit a cone air filter, a single box center exhaust, then you'll became deaf in no time...
I see, so a cone air filter, single box exhaust.
what about manifold etc etc.
also i see on minispares about downpipes and that do these affect the noise?
