Yoshimura RS-4 Slip-On Exhaust

Baker600 - Houston TX
5 out of 5 stars
Looks great "First Yoshi I have ever put on a dirt bike. It was bought for looks more than power gains on the 2020, YZ450F. It sound great, from tickover to flat out. Great price from Motosport.com made it a no brainer over the other options. The only negative is, the side cover is real close and its going to need a little remodeling with a heat gun to get it off the hot pipe."

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.

Dirt Bike Muffler Brands

MotoSport stocks a wide range of dirt bike mufflers from only the most respected industry brands that offer hefty upgrades on limited budgets to those who can afford what the pros ride. The benefit to upgrading the muffler on your dirt bike includes an increase in power, lighter weight and most everyone's favorite the awesome throaty sound. Check out just a few of the more popular dirt bike muffler brands:
