B91 1" Exhaust Silencer ( muffler ) fits 1" OD 4 cycle pipe. Clamp is included.
Don't let the name "Silencer" / "Muffler" fool you, it is designed to help give the engine a little extra torque, it does in fact take the edge of the POP POP during deceleration, but it's still LOUD.

It's loud, but good aesthetics.
reduced back fire and quieted it down so the neighbors don't complain but still loud. You may have to cut the tip off for it to fit depending on your header
It's a heavy duty muffler! Looks like it should flow really well; so giving up the racket of a straight pipe shouldn't hamper performance much at all. HUGE drop in noise over an open header.
The muffler make my go kart sounds good.
Love it. This was mounted on a 41 year old 10hp Super Bronc which now sounds like a vintage street bike.
Much quieter !!!
