ok guys i bought my bike from the dealer with the roadhouse exhaust on it. everything else is stock, and i havnt changed any settings. the dam muffler is starting to look like crap. the rest of the exhaust system is fine, but where the muffler connects to the rest of the pipes, its getting discolored severely. the rest of the muffler is randomly getting what look like patches where the paint/powder coat is coming off. WTF is going on here?? any one else have any issues like this?
