Yoshimura 961-8101 Signature Rs-2 Full System Exhaust Ss-Al-Ss

replaces entire exhaust. fits just like factory. even uses original heat shield. noticeable power improvements. a little louder than I thought it would be but it sounds great. I've seen other companies exhaust systems and not been very impressed. If you want top notch quality, get this one.

I just installed this system on my 2003 kfx 400, the quad was stock except for the uni filter. After installing the exhaust and the Dynojet kit I noticed a decent power gain and I still have a little fine tuning to do. It also looks and sounds great! One thing that was a plus with this system is that the stock heat shield can be used with the header pipe. I previously owned the same exact quad i have now which had a White Bros e -series full exhaust on it and I burned my leg on the header when i was riding with shorts. The only problem i had with this system was I havent been able to get a torque wrench to one the bolts that mount up from the cylinder head to the header. Basically im satisfied with my purchase.

What is it to say just what one person needs the upgrade of a exhaust system.
