    Excellent full system for the price
    Really happy with this system. Replaced my toasted Yoshimura silencer with the DRD and couldn't be happier. I don't feel that my 450 needed or needs more power but the DRD did smooth out the delivery and gave the bike pretty good snap off the bottom. Would certainly consider DRD again!

    Awesome but the exhaust tip is absolute garbage
    I have a 2015 model but that wasn't an option yet. This exhaust added a good deal of throttle response to the mid and lower end of the rpm range. I would highly recommend it. Be very careful during assembly as the POS black paint job on the muffler tip will scratch if you look at it too hard. Guess they had to cut corners somewhere to offer it at a somewhat reasonable price tag. If you really want to get the full benefit of this exhaust pair it with the ktm ignition switch and set it to the more aggressive setting. Very noticeable power gains.

    What is that cylinder on top of the header for?
    Michael C on Sep 20, 2016
    BEST ANSWER: It's a resonance chamber used on some machines both to reduce DB and tune the power at a certain point in the powerband.
