The back box silencer is blowing on my 2007 Cooper Conv. Is there a box I can replace it with that will give it a sportier sound ? I don't want it neighbour waking loud but a bit throatier would be good.
I replaced my R50 exhaust with a JCW one. Supplied by BMW and was around £350 IIRC. Sounded nice, not too loud but definitley sportier. I wouldn't trust many other aftermarket backboxes, the ones I've heard have been a bit boy racer-ish.
