BMS Stage 1 and Exhaust combos?
Hey everyone brand new 2013 BMW 328i owner and also brand new to the forum. I just ordered the BMS Stage 1 tune and am very excited however I was curious if anyone had after market exhaust systems with there tune.
If so how do you like the tone and what are the gains? |
