Product Description


Yoshimura RS-2 Signature Series Slip-On Exhaust

Yoshimura Signature Series exhaust components are the answer for riders faced with ever-tightening noise and emissions regulations at the federal level. All Signature Series components are independently tested, documented, and marked as required by state and federal regulations as CARB/EPA-compliant.

The RS-2 slip-on muffler is a potent and versatile design that evolved from Yoshimura's original TRC, engineered to provide increased and better power delivery. With a different pyramidal shape that increases volume over traditional muffler shapes, the RS-2 is a quieter system with a larger core and outstanding performance.

  • Diamond-shaped muffler sleeve
  • Large core and increased muffler packing volume means quieter operation
  • Cone-shaped end-cap
  • Stainless steel tail pipe
  • USFS Approved spark arrestor
  • Includes instructions and all required installation hardware
  • 80dB EPA noise emissions compliant

Questions & Answers

  • Do you need to re-jet to use this slip on.

    By: Chris

    While it's not required, if you want to get the best possible throttle response and engine power output, you should certainly re-jet your bike upon installation of this, or any other exhaust component we sell. This holds true for headers, slip-on mufflers or full exhaust systems. Of course, you can give it a try without re-jetting and see how the bike performs, but if you want to maximize your investment in an exhaust, again - we recommend adjusting fueling.

    We have a variety of Dynojet Carburetor Jet kits available that'll work with the RS-2 slip-on muffler. Each kit includes everything you need to set up fuel delivery for that slip-on and also, clear instructions as to how to fine-tune the carburetor to get the best that exhaust has to offer.

  • Will this fit my 2013 king quad 750?

    By: Chris

    Yes, we do have a Yoshimura exhaust for the 2013 Suzuki King Quad 750. Just choose the LT-A750X KingQuad 750 AXi 4x4 exhaust or LT-A750XP KingQuad 750 AXi 4x4 EPS exhaust system from our fit guide to get the correct system to fit your exhaust machine.

  • Will this muffler fit on the stock header pipe on the 150r

    By: Guest

    Yes, this muffler will indeed bolt straight up to the OEM muffler on the Honda CRF150R. In fact, all Yoshimura slip-on mufflers are designed to work with the stock exhaust system for an easy installation, every time.
