Hello guys! I purchased myself a lovely E46 318ci coupé today which I already adore. Its the 16v 2.0l version in black which is in fantastic condition despite its age and mileage. However there was a couple of issues, one being a big hole in the backbox. Seeing as I need a new one I feel like I should spend a little extra to get a more sporty sound from it but I'm not sure where to go since this is my first BMW. Could you guys point me in the right direction, I don't want to spend a lot of money, the cheaper the better really and its only the backbox I need but I also don't want a cheap universal one. I'm also quite interested in changing the air filter to make it sound a bit more meaty since its only the 2.0l so any help or suggestions on that would be brilliant too. Thanks, Jamie!
