Description: The RS-4 is pentagonal shaped muffler that features a carbon fiber cone end cap, two staged stepped baffle and striking good looks. A tapered header pipe design is used for optimal flow and performance. The RS-4 not only increases power and is light weight, but it also has a lower centralized mass coefficient to provide better handling. The RS-4 muffler features a new front cap design that functions as a polyresonant chamber. This design makes for a quieter muffler with improved mid to top end power. Pro Series Full Systems include an RS-4 muffler with Titanium or Carbon Fiber sleeve, titanium header and tail pipe, AMA Pro Racing insert, all necessary hardware, and detailed installation instructions to get you moving. Pro Systems come with an AMA Pro Racing sound insert installed in the muffler. Note: System for 2010 RMX450Z includes a Yoshimura "Cherry Bomb" coax relay bypass module, which is a plug-in module that maximizes engine performance in minutes by optimizing engine management parameters. Quick and easy to install. Important Notes: **Some products may not be legal for sale or use on pollution-controlled vehicles. Check your local laws and the manufacturers information. **It is recommended that new exhaust gaskets and a proper jet kit be installed when changing an exhaust system on a carburated motorcycle, or new exhaust gaskets and a digital fuel processor when changing an exhaust system on a fuel-injected motorcycle. **There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing) is caused by tuning characteristics, like cam timing, carb jetting, etc., and is not caused by defective manufacturing.
