For a no-compromise exhaust system with great performance, check out the all new Ti-4 GP low boy system. Constructed of durable high quality grade 2 aerospace titanium, this exhaust system is built to provide huge weight savings with unique highlights. Here's a complete front-to-back system using ultra lightweight Grade 2 aerospace titanium throughout. There are huge weight savings with this one, along with a boatload of performance highlights. This system was especially developed to lower and centralize a bike's center of gravity, therby improving overall handling and increasing critical clearances. And power? Crack the throttle and the Ti-4 instantly responds with an immediate hook-up, building from there with horsepower gains all the way to the top.
