Can anyone give me there thoughts on the above exhaust pipe companys, as i wish to replace my old system, also do any of the above do oval boxes? and one last silly question what is the difference between back box, silencers, mid boxes apart from where they are positioned????
sorry to sound so dumb
ps if any of you have a custom system on your car what did you go for as in type of boxes and size of tube and tail pipes as i have the 328i touring
