About to put on the Dinan Black Tipped Exhaust on my 2013 F10 550xi, so that is my favorite Performance part right now! Tried another brand and made the car sound like a Dodge Charger SRT.
Will post pictures and sound of Dinan after it is installed the forthcoming week. As always Jason at getbmwparts is the BEST for service and support!
Looking forward to getting the Dinan intake from you soon!
Hopefully I am the lucky winner and apply it towards the intake. lol
