M550i Downpipe

I am thinking of getting an ARM MOTORSPORT cat-less downpipe for my G30 M550i soon, but I have a few questions before I install it. My current set up is Stage 1 Dinan tune and resonator delete. Does the cabin smell at all? How much is drone when it is idling/driving? How loud is it under comfort mode? Is it damaging to my muffler since the car is almost straight piped? Would you recommend me getting it?
