M5 Competition Muffler/ Dinan upgrade
Looking to upgrade my F10 550i exhaust- unlike many people, not looking to make it extremely loud, seen posts that say M5 competition muffler will add some sound compared to my stock...the other option is the dinan free flow axle back exhaust although a bit much for budget.
Anyone Norcal-bay area with this setup willing to show me what they got? or anyone have the M5 competition muffler for sale?
Cheers!
