You got two options, get a DG RCM replacement exhaust spendy but they sound soooo nice, or an EXSound slip on muffler that retains the original head pipe. Denniskirk carries both options for it. There is the MBRPP slide on muffler to, but side by side with the EXSound ones they look the same in person, i think its just a branding thing. Again neither option is cheap, but they work better then a rusted out original or a straight pipe... lol
