Yoshimura RS-4 Slip-On Exhaust Kawasaki ZX6R 2009-2012

Yoshimura R&D has developed a brand new exhaust system for the newly redesigned ZX-6R, the RS-4.

While the RS-4 was debuted as our 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: This exhaust is CARB compliant. Please check local laws before purchasing. Some modifications may be prohibited in some states.

Quality Product It's still wintertime so haven't had much time to fully test the exhaust. It was simple to put on and feels like a quality product. Total install time was maybe 30 minutes. I've ridden maybe 30 miles with the silencer in and it sounds perfect. Slightly deeper tone and a little more throaty than stock. No noticeable power difference and didn't expect any. I bought for the price and value per dollar which I think was properly advertised. Looks better and weighs less than stock. March 4, 2014
Beautiful exhaust! I had my slip-on options down to the TwoBros, and the Yoshimura RS-4. I choose the RS-4 because I was worried about noise. After the install, which was very easy, I'm happy for my choice. I love the looks, and it's only slightly louder than stock. I was also surprised to feel an extra kick in low gear on acceleration. Beautiful exhaust, and it does what it's supposed to. January 5, 2014
Great exhaust with a few issues The exhaust is great, sounds great, looks great mounts great! BUT the clamp on the exhaust is too big and allows for the exhaust to basically move freely on the header pipe. The clamp cannot be tightened anymore as it has bottomed out. Also. The positioning of the exhaust directs exhaust gasses at the left rear side reflector and guaranteed will melt it as it did mine. October 18, 2013
Solid slip on The only thing I was dissapointed in was the craftsmanship of the mid pipe. Pipe slipped inside the other pipe, then wire fed. Positive: nice sound, can looks good, easy installation! October 14, 2013
exceptional value, awesome look, and awesome sounds Bought this for my 2011 zx6r, the installation was very simple, and really anyone could do the job..the only tool someone may need is the security torx bit to remove a screw for throttle servo. 9.00 at home depot and total time involved was less than an hour start to finish.

Sleek, nice sound. I finally rode a few hundred miles to give an accurate evaluation of the Yoshi RS-4. I chose the Yoshi for its adaptability to the my 2009 ZX-6r’s existing ECU map, its slightly louder sound, streamlined, sleek look and its bang for the buck. The bike sounds perfect, IMO, and has a nice growl when on it but quiet enough so it won’t attract unwanted attention. It a bit lean when totally off the gas due to better flow and the elimination of the stock restrictor valve, actually I like that as well. It seems to run a bit stronger throughout the RPM range. Appearance wise it’s fantastic compared to the stock behemoth! Finally RevZilla’s price, return policy and free shipping made the choice an easy one. May 1, 2013
The exhaust comes easy to go out of the box. This exhaust is great sound through all the power ranges. Easy to install with all the parts you need. Not extreamly loud. March 25, 2013

Steven P: Super Tenere installation. Let's be as accurate as possible when we are trying to answer questions those interested in purchasing post. I can't think of a better way to assist others in spending money than to provide responsible information in this forum. I installed the Yosh RS-4 exhaust system today. Weight of stock exhaust 12lbs. Weight of Yosh with silencer installed 6.5lbs. Quite substantial as a percentage but 5.5lbs is accurate. Scale accuracy is based on the difference not exact weights as I did not calibrate to the oz. The net weight savings is 5.5lbs! May 21, 2014
