19+ Bmw X6 50I Muffler Delete, Pics. It sounded quite mean but cold starts weren't too pleasing and the drone between shifts were annoying. I have just a muffler delete on my 09 e90 328i.
I did the muffler delete yesterday and replaced it with two separate straight 2.5inch pipes.
It did drone on the highway but it didn't really bother me. This muffler delete is one of the most cost effective exhaust modifications available for your n54 & n55! A muffler delete is exactly that. Deleting my mufflers has crossed my mind before, but i just never got around to it.
