Does anyone know if the Stage 1 AR Motorsport Upgrade Kit is ordered when purchasing the M3W (hence, factory-fitted), are the baffles removed or does the kit have no influence on the exhaust at all?
I have got the Mog stage 1 kit fitted and I think there are only few restrictions inside the pipes. Far better breathing and fun to drive. Some additional noise too...
As far as I know: it is a completely different exhaust than standard.
Hannes once: Green M3W; 2013 now: Red 4/4 Sport; 2011 and some practical cars for use in real life
