1 pc. Muffler kit for Honda twin cylinder engines.
K1 series. Not for older K0 engines.
Exhausts on right side of engine when looking
at the crankshaft. (oil filter side).


Note: K1 Series engines have 1 bolt that hold the valve
cover on. K0 engines have 4 bolts that hold the valve
cover on. You can also tell the difference by looking
at the air filter assembly. The new K1 series has 4 clips
that holds the filter cover on, the older K0 style had a
bolt that goes into the center of the filter cover.
We no longer sell K0 engines or muffler kits.
