Dirt Bike Muffler

Confusion often surrounds the dirt bike muffler. Is it the pipe? A slip-on? Silencer? The full exhaust system? A 4-stroke dirt bike uses a muffler, also called a slip-on, and represents just the end part of the full exhaust system. On a 2-stroke, it's called a silencer. Regardless, most riders if that don't want to upgrade the full exhaust system, invest in a dirt bike muffler for their 4-stroke.
