I'm really enjoying owning my 323i and if I'm honest with the hood down it is plenty quick for me but I do hanker after an M3 Vert (not yet though ).
One of the things I think is a bit wimpy is the sound the 323i makes when accelerating but I don't know the first thing about how to make it sound more throaty/aggressive/roarty etc. etc.
Is it a change of exhaust or is there something simpler I can do like change a few filters or somesuch things?
All advice much appreciated
