If you're looking for increased performance, there is no faster (or less expensive) way to get it than a Pro Circuit Slip-On silencer. The Ti-4 Slip-On raises the standard of excellence in both appearance and performance. It offers huge performance gains when compared to stock O.E.M. exhausts, lowers the center of gravity of the bike, and these silencers will bolt on to the stock or Pro Circuit head pipes in a matter of minutes.
In addition to the extra power, the Slip-On Ti-4 silencers are substantially lighter and are designed to be easily re-packed to keep performance at its peak. The Ti-4 Slip-On features complete titanium construction and the ultimate in weight savings. The unique design offers extra durability and personal comforts. Horsepower and torque are increased throughout the entire power curve.
