I'm looking at finally getting around to putting a muffler on my 540, and I was wondering since they sell dual-out diffusers for the M5 rear bumpers... how in the heck do you route a muffler on the passenger side? (US passenger side) Is it just me, or is the gas tank REALLY in the way on the passenger side?
