I purchased my RB mufflers 3 months ago. Being a bad owner that I am, I already wore the mufflers down. The edge of the muffler tip is showing burnt marks (but i am not shooting flame). What are good ways to clean it up?

 

Try simple green and a brush.. use a little elbow grease and they should clean right up.. i put chrome polish on them one time, looked good and stayed cleaner for a little longer.

 

I just have stock right now, but I used wheel cleaner and a little scrubbing pad and it worked great.

 

S.O.S pads work wonders
