Quick question, but does anyone know what the difference between the exhaust system on the 325i is to a 330i?
I have read that alot of people think the 330 sounds better than the 325i, but as far as i can see the exhaust system is the same bar a vacuum operated flap??
Surely the flap would make it quieter, and not better??
Are the baffles reduced/ rearranged inside some how?
