Yoshimura RS-4 Exhaust features:
RS-4 STAINLESS/ALUMINUM FULL SYSTEM: As the official exhaust of the Rockstar Makita Suzuki Yoshimura Supercross/Motocross team, this exhaust was designed with one thing in mind, winning races. The RS-4 is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance.
This Full System comes with a stainless steel header and mid-pipe, aluminum muffler sleeve, installation hardware, and detailed instructions to get you moving!
Stainless Systems come with a USFS approved Spark Arrested insert installed in the muffler
PIM2 Unit (2010-2011): Yoshimura introduces PIM2, the evolution of our original Dirt Bike/ATV fuel injection adjustment “PIM” device. PIM2 installs easily, typically in under 30-minutes using simple Plug-N-Play technology. Plug the PIM2 into the stock wiring harness, mount to your bike using the supplied mounting kit, and you are ready to race! The PIM comes pre-loaded with two separate fuel injection maps for either a Yoshimura Slip-On or Full Exhaust System. But the adjustability is limitless and easy. If those two maps are not enough - there are dozens of maps to download for FREE on our website (yoshimura rd).
