Flowmaster mufflers
 

Anybody know if Flowmaster makes mufflers for the X5's? :D:D

Nothing direct fit, but you could have some custom installed. I considered putting a dual in/dual out muffler (either flowmaster or magnaflow) in place of the center resonator and putting short bullet resonators in the rear where the current mufflers reside... But I may not be keeping the X5 for too much longer (much longer commute to work, rearranging things in life) so haven't done it yet.
