My M3 E90 with Akrapovic evolution (titanium exhaust system)
Tried exhaust mod, didn’t like the sound.
Tried Supersprint race, waaay to loud and drone!
And m performance, very good but a little to silent and hatet the looks of it looking at that big hump u underneath.
This is the best there is, perfect tone, not to bassy, and most important, no drone!l
Long motorway trips are no problem at al, and when pedal to the metal a rich and full sound but never to agressive.
