About This Product
MCS zinc-plated steel reducer sleeve. It steps a 1-3/4 inch muffler inlet down to a 1-1/2 inch head pipe. You need this on 45 inch Flathead models when fitting a larger muffler than stock. It gives a snug fit so the joint does not leak. Matches OEM 508039. Clamp it properly and check for leaks once the pipes are hot.
Manufacturer part number: 508039.
Fitment
45" (750cc) Flatheads with 1-3/4" diameter inlet muffler
