Fitted a new exhaust on my S550 at my boys workshop (well I only watched, supervised & laboured)....Magnaflow Street...very happy & glad I didn't choose the "competition" system, street is quite a bit louder than stock. thanks to "EXHAUSTED" for his recommendation.
The original system was painted black & once removed, unveiled that it had been spray painted in situ as the top of the system was bare metal....guess that's what we can expect from a sausage factory....
