Add some fire to your rides with Yoshimura's Comp Series RS-2 full exhaust system. This Full System comes with an Aluminum muffler, a stainless steel header and mid pipe, installation hardware, and detailed instructions to get you moving! Yoshi also includes a cool looking laser etched heat shield for the header, and a USFS approved Spark Arrested insert comes pre-installed in the muffler. Fit and finish is typical Yoshimura, and it looks downright awesome on the bike. The system has a very deep tone, and sounds, frankly, bad a$$.
We also allow you to optionally add a Jet Kit (either Dynojet or JD Jetting) to get your bike running correctly and help take advantage of the new performance exhaust system. You can also add a Kientech Fuel Screw and either a No Toil or K&N Air Filter to the package as well.
FITMENT: 2000-2018 Suzuki DRZ400S and DRZ400SM
We have the carbon fiber version of this system on our DRZ400SM Project Bike, and love it. Besides the exhaust system, we also did the 3x3 airbox mod, replaced the stock air filter with a K&N air filter (see option below), and jetted the carb with a Dynojet Jet Kit (see option below). These relatively simple modifications totally transformed the performance and sound of our bike and we highly recommend it for any DRZ400S or DRZ400SM rider! After installing the exhaust, filter, and doing the 3x3 mod, we had the carb jetted and tuned at our local race shop (MPH Ohio) and here are the results...
Stock 2008 Suzuki DRZ400SM (According to Motorcyclist Magazine) Max horsepower: 32.5 bhp @ 7850 rpm
Max torque: 23.9 lb.-ft. @ 6750 rpm
Our 2008 Suzuki DRZ400SM Project Bike (without Dynojet Jet Kit) - SRmoto.com Yoshimura RS-2 Performance Package
- 3x3 Airbox Mod
- Carburetor NOT re-jetted
Max horsepower: 34.01 bhp @ 7200 rpm
Max torque: 24.41 lb.-ft. @ 6400 rpm
Our 2008 Suzuki DRZ400SM Project Bike (with Dynojet Jet Kit) - SRmoto.com Yoshimura RS-2 Performance Package
- 3x3 Airbox Mod
- Carburetor re-jetted with Dynojet Jet Kit
Max horsepower: 36.27 bhp @ 7200 rpm
Max torque: 28.57 lb.-ft. @ 5800 rpm
Overall we are very pleased with these results considering how simple these modifications were to do to the bike. The numbers above show the importance of properly jetting the carburetor with the appropriate Jet Kit. Without that, the bike ran poorly, and as you can see from the results, we weren't maximizing performance gains from the Yoshi exhaust, aftermarket air filter, and 3x3 airbox mod.
