Yoshimura RS-2 Stainless Aluminum Exhaust
The Yoshimura RS-2 Stainless Aluminum Exhaust is delivered with a complete kit that includes mounting hardware and well written installation instructions. Yoshimura is well known in the ATV exhaust industry and in my opinion this years RS-2 exhaust system is on par with past stainless and aluminum models made by Yoshimura which just happens to mean they are among the best available for your sport ATV or Quad.
Yoshimura RS-2 Stainless Aluminum Exhaust Dyno Test Results vs Stock
Yoshimura ran a dyno test of the RS-2 Full Exhaust System on a 2009 YFZ 450r ATV vs the stock exhaust system and muffler and as you can see the Full Yoshimura RS-2 Stainless Aluminum Exhaust system yields an increase of 2.3 maximum horsepower and 1.6 lbs of torque. The dyno test on the Yosh RS-2 exhaust was run with a 96db sound insert USFS approved spark arrestor but 94db and 99db inserts are also available.
Power gains lean towards improved full throttle high RPM response meaning they allow an ATV engine to breathe more freely at top speed. MSRP is currently $595.00. Here are some similar Yoshimura exhaust sytems at auction to help with price comparison.
