i bought an MPE from someone on here and so now i have my original stock muffler for the f30 335i with the black tips.
Just a quick opinion (totally my opinion lol). the MPE is ok, but i think i might actually like the stock exhaust with both flaps open over the MPE. seems deeper and cleaner. i even did the exhaust flap mod on the MPE and i still think i might prefer the sound of the stock with the flaps open.
I live in Atlanta and i will do a local pickup or i guess we can try to work shipping out.
