These should work !!
Replacement muffler generic jc whitney
Dont worry I have 54,000 on mine & the engine case has yet to be cracked open !! ( fingers crossed)...
Yeah...they work, but they start rusting in the box. Cheapest chrome I've ever seen in my life, and they're already rusting enough on the inside to make early morning condensate come out bright orange. Nothing like the OEM Sanke's (NLA) which literally rot off with the chrome still shiny.
I'd opt for some Hardley take-offs before getting those, they're POS IMHE.
