need a bit of advise, just bought a 2017 s55o and would be interested to find out which would be the best after market exhaust - think I have already decided on a cat back but not sure which manufacturer, like a good bit of sound but not too loud on the longer roads, thanks!!1
hi guys, thanks for the feedback - think I k=have decided on a borla s type cat back would your advise to import directly from the states or buy from a dealer in the uk, thanks john
