browsed through the older posts looking for recommendations for a
sport exhaust for a 2003 325Ci coupe. I contacted a Beemer auto-sport
shop and the guy recommended not to change the whole catback system,
just the muffler.
when changing exhaust systems, it is ok just to change out the muffler
or changing the whole cat back system is better?
any good performace exhaust (besides the pricey AC-Schnitz) that is a
little sporty in tone but not loud enough to give me a headache?
thanks in advance
