I was thinking of getting the mtech rear bumper and i don't want to be driving around without the quad. Is it possible to add another muffler to my 2004 530i or do i need to replace the whole exhaust. Any inputs would be greatly appreciated.

I believe Remus makes a quad tip for 530i

Some members here made custom exhaust to make theirs quad. However, some may say that going to quads my reduce power.

Also there was a long thread here with a title something like "truth about quad exhausts". Not sure what the exact title was but discussus a way a member made quads without losing power.
