Pro Circuit TI-4 GP Complete Exhaust System - Features
These exhaust systems are dyno and track tested by riders like James Stewart, Ricky Carmichael and Ryan Villopoto as a no-compromise full-race exhaust. The ultra-lightweight titanium Ti-4GP is our premium exhaust system and it includes Pro Circuit's titanium header pipe. The Ti-4GP exhaust will boost performance from bottom all the way to the top end, making it easier to ride and lowering lap times. The silencer can is easily repacked simply by removing the inlet cap screws and re-wrapping the silencer core. The Ti-4GP meets all AMA sound restrictions. This is the exact same exhaust system that won four out of five AMA National and Supercross titles in 2007.
