Yoshimura RS-4 Race Series Full Exhaust System
If you're looking for that competitive edge, look no further than Yoshimura's Race Series exhausts. These exhaust components are designed with nothing but power in mind. Each Race Series system is developed in accordance with noise compliance regulations imposed by most race sanctioning bodies worldwide.
The work that went into developing the RS-4 muffler design paid big dividends during development in AMA Pro Racing. That research was directed at developing the RS-4's unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 muffler features a polyresonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end cap.

Questions & Answers
Which exhaust is good for a 2016 ex 650 ninja touring
You'd probably find that just about any Ninja 650 aftermarket exhaust we sell is an improvement over the stock Kawasaki exhaust. This is down to the fact that OEM exhausts are rather heavy on account of the catalytic converter and also, the amount of internal baffling used in the muffler. Both of these are required to meet ever-tightening sound and gas emissions requirements.
Also, if you want to get the best possible throttle response out of your bike, we highly recommend that you also adjust fueling to suit in the form of a Bazzaz Z-Fi fuel controller. That device, combined with the Yoshimura full system, will get you more power and the bike won't stumble when you grab a handful of throttle since fueling can easily be matched to the exhaust.
