Yoshimura - RS-4 Exhaust System (Yamaha)

Yoshimura R&D has developed an evolutionary new exhaust system. The all-new Yoshimura RS-4 was designed after extensive testing and the results are profound.

The Yoshimura RS-4 exhaust system was designed with one thing in mind, winning races. The RS-4 is a unique design with predicated power, and a quiet earthy exhaust note that speaks volumes for performance. It was an obvious choice for the  Yamaha YZ250F and YZ450F.

Pro Series Full Systems include an RS-4 muffler, titanium header, Titanium or Carbon Fiber tail pipe, AMA Pro Racing insert, all necessary hardware, and detailed installation instructions to get you moving.

    Comments about Yoshimura - Pro Series RS-4 Full System (Yamaha):

    My wife purchased a 2016 60th Anniversary Yamaha YZ450F for me. First and foremost, I typically ride street bikes and typically stick with akrapovic exhaust system. After riding my new dirt bike server all times, I decided I wanted an exhaust. I was originally looking at FMF as they are "off-road exhaust kings", after talking with a friend at Mountain Motorsports in Marietta, GA I decided to go with Yoshimura and I can't tell you how happy I am with this exhaust. First of all, they provide all the necessary extras you will need to perform the installation like heat shield material and spring puller. The exhaust is sure nice, easy to install and provide great throttle response. I've performed two test rides with two different maps in my power commander V and only stalled once, with my stock exhaust I stalled all the time. I can't put into word the fit, finish, sound and performance this exhaust provides. I told several friends I ride much better with this exhaust than stock. I super highly recommend this exhaust system. The power commander v is also a very nice unit.
