The Ti-5 Race Systems are constructed of titanium throughout the muffler can, header and mid-pipe areas. Designed for optimum performance, riders will enjoy increased horsepower while still meeting both AMA and FIM sound requirements. Unlike other Pro Circuit exhaust systems, the Ti-5 offers consumers the choice between a titanium or carbon fiber end cap. Additionally, the asymmetrical muffler configuration maximizes packing volume to ensure sustained performance.

•Asymmetric muffler design
•Meets 2012 AMA/FIM 2-Meter max sound test
•Increased packing volume
•Aluminum muffler bracket
•TIG welded
•Comes with RC-4 Resonance Chamber
•Machined titanium mid-pipe to header joint
•Optional titanium or carbon fiber end cap
•Additional silencer packing kit included

Pro Circuit now offers a replacement Carbon Fiber End Cap for Ti-5 Exhaust System mufflers that originally came with a carbon cap. The Carbon End Cap was designed in house and are made with twill carbon fiber cloth. During manufacturing, the end caps go through an autoclave process that uses both heat and temperature to ensure that the parts are as dense, uniform and free of air bubbles as possible. This combination of high strength materials and advanced manufacturing processes allows Pro Circuit to make an extremely lightweight part that showcases the weave of the carbon cloth without sacrificing strength or durability.

The asymmetrical muffler configuration maximizes packing volume to ensure sustained performance. Specifically for international customers, the T-5 Euro System meets the FIM 2 meter max sound requirements.

The Pro Circuit Keychain/Taper measure is probably the absolutely most highly prized item in the MX/SX world. Here's why: guys buy this keychain. Then they have their hair dyed red, an ortho makes them shorter by removing spinal discs, then they top it off with plastic surgery. End result: they look just like Ryan Villopoto. After a race, they go to a bar, toss the Pro Circuit Keychain on the counter...chicks fight over who gets to be first...and well....you know the rest.
