SSB took its 2009 Kawasaki ZX-10R to the dyno with a full exhaust system from Leo Vince. Not only did it drop six pounds, but it picked up 6 HP over stock, bringing it up to 161 HP at the wheel. Midrange gains were massive and a big improvement over stock as well. Note the blue flame that shoots out at the end of the dyno run…sick! See more exhausts at www.leovinceusa.com.
