Mackpro Posted April 12, 2011 Share Posted April 12, 2011 could my muffler be full of soot???????????I did have a baffle come loose and block off flow on an ASET, ran like crap. It had the stand up muffler though. Yours has that frame mount laydown style. Something better could be rigged! Quote Link to comment Share on other sites More sharing options...
