Good To Know

Q: Will this muffler work on a carbureted Vanguard Big Block? A: This muffler is designed for EFI models; carbureted engines may have different exhaust port spacing or bolt patterns, so you should verify the part number 846819 in your engine’s IPL.

Q: Does the muffler include a gasket or hardware? A: The muffler ships as the main body only; exhaust gaskets and mounting bolts are sold separately and should be replaced if they show signs of wear.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
