PRO CIRCUIT'S Ti-5 Race System exhaust for the Honda CRF150R reportedly allows riders to enjoy increased horsepower while still meeting 2-meter max sound requirements.
Constructed of titanium throughout the muffler can, header and mid-pipe areas, the Ti-5 is available with either a titanium or carbon fiber end cap. An asymmetrical muffler configuration maximizes packing volume to ensure sustained performance, according to the company.
Also available for the CRF150R is Pro Circuit's T-5 stainless GP Race System and the T-5 stainless slip-on silencer. The T-5 features an aluminum can, stainless steel tubing, cap and performance tip. All these systems have a USFS-approved spark arrestor and the same asymmetrical muffler configuration as the Ti-5.
