Piets94 are you still by chance running your HMS setup? i've been browsing through axle-back exhausts to put on the M and i saw your videos, love the sound of your HMS exhaust, and your review. do you still feel like an axle-back would be enough for the car? our cars definitely sound good i just wish i could hear our exhaust notes and that signature burble a little louder, thanks in advance and hope to be hearing from you
