Buggies Gone Wild Golf Cart Forum - View Single Post - 1986 Marathon. No power unless muffler removed

Justinh722 · 10-12-2021, 10:11 AM

I’ll post an update for anyone curious. The muffler had an internal breakage that caused the baffling to get hung up not allowing the exhaust gasses to exit like it should. So requiring a new muffler and with all the reliance mufflers being on backorder, it looks like I may have to just buy a muffler and fabricate my own. The factory muffler is 12 1/2” long by 6” in diameter. I found a farmall tractor muffler 13 inches long and similar diameter that I can just close off one end and weld in a flange to the side and figure out the tailpipe routing.

Unless anyone knows of a better option as the powerband of the engine comes from the header design I believe it should work.
