    Exhaust theory on N54 & turbos in general

    I wanted to talk exhaust theory and get some opinions from people: I've been reading a lot on these forums and it seems that most people are content with the stock exhaust (modified or not) or go with single 3" systems. This kind of bothered/confused me because I always read that the lower the...
