335is Dinan Free Flow Exhaust
I have a 2013 335is coupe. Did a s2 dinan performance upgrade. Just put on the Free Flow Exhaust with black tips. The sound of the cold start up is amazing because its a deep put (similar to the sound of a v8). However driving, barely hear it. I think I got spoiled with the fine tune of the stock exhaust. On the other hand, the car does perform much better.
Any ideas to make it louder?
