Hello there, just brought a BMW 318 ci coupe a fortnight ago. The car has some tacky Chrome tip on that sticks about 4 inches out of the car. Looking for a cheap full system or even a backbox? Just wanting to find out some recommendations so I get something good. Also not sure on what will fit on the car like 330ci/m3 or any 3 series exhausts or the kind of aftermarket etc!
