Yoshimura Works R-77 Race Series 3/4 Exhaust System


If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.

Yoshimura's 3/4 exhaust kit includes an R-77 muffler, stainless steel mid-pipes up to the stock header, all hardware for installation, and detailed step-by-step instructions.

Yoshimura's Works Finish takes on a unique coloring after it goes through a heat cycle on the machine that looks much like those titanium works components many factory racers use.

  • Contemporary satin/matte finish
  • Uniform heat coloration
  • Increased fatigue strength
  • Increased scratch and stain resistance

The R-77 delivers better performance overall because of the larger volume of packing material available that's inherit to its design. You'll notice great sound that come from the R-77 muffler. It's not loud, but a rather nice and throaty.

  • Trapezoidal Shape
  • Removable low-volume insert
  • Eliminates the heavy catalytic converter
  • Maximized muffler volume
  • Innovative end-cap shrouds the terminus of the muffler for an unmistakable look
  • Made in the USA

Questions & Answers

Ask Question

Does this exhaust require a tune after installation

While you can probably get away with installing this Yoshimura Works R-77 Race Series 3/4 Exhaust System by itself, to achieve the best possible throttle response and engine performance, it's always best to install some sort of fuel controller. Basically, any time you change the way air flows into or out of the engine, you'll want to adjust the air fuel ratio accordingly to maximize any performance gains available from the new freer flowing exhaust system.
