DRD SA Slip On SS/AL YFZ450

Dirt Wheels Quote August 2004 YFZ Exhaust Shootout (12 different exhaust companies) "With quality, weight and price taken into consideration, the Dubach system is the clear winner" "With its low price, easy installation, strong power figures and music to our ears sound numbers, the Dubach Racing quiet exhaust system is the winner of the Yamaha YFZ450 slip-on pipe shootout. Congratulations."

Dirt Wheel Quote “it feels like you are riding a highly modified motor when running the Dubach system.” “It pulls amazingly hard off the bottom and super strong all the way through the mid and top end”

Customer Reviews

Average Customer Review

	Much needed power.
	The DRD Pipe, Slip on & Dyno kit gave my YFZ much more power without being irritatingly loud like some of my friends Quads. The directions for the main jet made it run rich. I had to reduce the jet 2 sizes, now it runs great.
