Yoshimura RS-4 Slip-On Exhaust

While the RS-4 was debuted as Yoshimura's premier exhaust for off-road racing applications, R&D couldn't stop there. They have mated this sophisticated and stylish muffler to compliment the styling of the new bike. The RS-4 is pentagonal shaped muffler that features a carbon fiber cone end cap, two staged stepped baffle and striking good looks. The RS-4 muffler features a new front cap design that functions as a polyresonant chamber. thus creating a more quiet muffler with improved mid to top end power.

Along with improving sound and power, this system moves the muffler weight lower and closer to the bike for improved handling and weight distribution. Yoshimura continues to provide the best in performance exhaust systems.

Slip-On Systems include RS-4 muffler, laser cut heatshield, and all necessary hardware for installation.

NOTE: Please check local laws before purchasing. Some modifications may be prohibited in some states.

Good sound, not loud sound This thing sounds good, I love it. I was pretty conflicted about what I wanted. With all the options, it was a hard choice, but now I am satisfied with it. On the zx6r, it looks 1000x better than stock, and sounds a hundred times better too. The loudness is similar, but the quality of the sound is significantly improved. I would like it louder so I ordered a link pipe, but even if it doesn't get much louder I won't be unhappy. If you don't want your bike much louder than stock, but want something better looking or sounding, then this is the perfect choice. You won't upset anyone with this pipe unless they just don't like the sound of a bike at all. The install was easy, but the instructions were barely adequate. I was glad I found install videos online to supplement them. What to do with the servo cables is really the only difficulty. I decided to buy a servo eliminator, so I did not need the included metal plate to attach to the servo motor. If you do plan to use it, make sure to have or acquire a torx tamper resistant set. The screw you take off to put the plate onto the servo requires it. The construction quality is very good though the heat shield that is included could be better. It is shiny black, not flat black fyi. I have not noticed any sort of gain or loss of power. I do not feel the need to gain power/torque, but I certainly didn't want to lose any. If you don't like the look of a short pipe, and you value quality over loudness, this may be a good choice for you. Ride safe! September 28, 2014
