Hi All,

Just wondering if anyone has changed only their stock mufflers to a performance muffler.

I am thinking of changing the stock muffler to maybe a Magnaflow Muffler. Currently my 08 X5 only uses 1 muffler but is there any reason i would need to have 2 mufflers? I'm also thinking of changing to an x-pipe rather than the H Pipe.

Any information is greatly appreciated.
