Vance Hines CS One Urban Brawler Dual Slip-On Exhaust for Kawasaki Z1000/Ninja 1000 2010-2011 The CS One Urban Brawler takes a minimalist approach in design that gives just the right look for a streetfighter-style bike like the Kawasaki Z1000. The dual slip-on application for the Z1000 is a dual-tip design available in either a polished or matte black finish, both sporting a laser engraved Vance Hines CS One logo. As a cat-back fitment on the Z1000, the CS One Urban Brawler puts out a nice throaty growl at a moderate sound level. Optional inserts can also be added to further temper the exhaust note . The CS One Urban Brawler slip-ons are a great value and an easy-to-install upgrade that really gives the Z1000 a trick look. And these Urban Brawler slip-ons will also fit the Kawasaki Ninja 1000. Made in the USA.
