Has anyone done a 535xi Muffler Delete? I am interested in a little upgrade.. Any other ideas are cool? How much does something like this cost?

Don't delete the mufflers, it's gonna sound like shit too raspy. Then there is always the debate of the back pressure and the HP loss, but like I said that's debatable. Oh and most muffler deletes I've seen drone like crazy also. If you want to improve the sound of your car and don't want to spend a lot just get a magnaflow muffler or something.

I guess I could just build a custom exhaust like another member was saying to do since i have a XI. Def don't have the $$ for 2-3000$ for exhausts. Rather get other things at this point.

Thanks for the advice
