Give yourself a competitive edge with the Race Series AT-2 exhaust systems from Yoshimura. These exhaust systems are designed with nothing but power in mind—and the sound of the Alpha-T 2 exhaust systems are absolutely unmistakable Yoshimura! Each Race Series exhaust system is developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide. In addition, the Race Series AT-2 exhaust systems' "Works Finish" takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components that Yoshimura's factory racers use. One look at a Yoshimura Race Series AT-2 exhaust system—plus, its sweet exhaust note, you know it's something special! Key features and benefits: * All applications are marked with appropriate EPA noise emissions labels * Noticeable gains in max horsepower and max torque * Sheds weight compared to stock exhaust * Stainless steel construction with aggressively styled carbon fiber end cap and uses a facet-formed tip matte carbon fiber heel guard * Yoshimura "Works Finish" for lasting durability; uniform heat coloration really gives the system a titanium look when it's been through a 15-20 minute heat cycle * For closed course competition only; not intended for street use; has not been tested for EPA noise compliance

Sonnax Smart-Tech input housing kits address the weak areas of 4-speed automatic transmissions. Flexing and bowing of OEM and other aftermarket backing plates is eliminated with Sonnax's heavy-duty bolt-on anchoring plates. Their unique design ensures even clamping of the 3-4 clutches in higher horsepower, higher pressure applications. By eliminating the 3-4 snap ring and using a thinner, yet stiffer apply plate, space is made available for additional frictions and steels. This makes it possible to simultaneously increase clutch torque capacity and eliminate the possibility of retaining ring blow-out. A steel reinforcement sleeve prevents breakage in the spline area. Housing fatigue/failure-resistance and housing life are significantly improved with a special treatment process that greatly reduces stress crack formation.

Failure of the intermediate stub shaft and direct drum are almost inevitable when transmissions are pushed to the limit. To maximize durability and improve clutch capacity in heavy-duty/performance vehicles, Sonnax offers Smart-Tech direct clutch drum and shaft kits, the first upgrade to eliminate every critical weakness. Most failures in these units occur where the direct drum and stub shaft connect. Even other aftermarket upgrades that rely on a heavy-duty shaft will sheer in this area under extreme conditions. Unlike two-piece assemblies, the all-in-one Smart-Tech easily handles the highest horsepower/torque levels. The unique one-piece clutch drum with integrated stub shaft is precision machined from high-strength steel to guarantee there are no splines to strip from the drum or weaken the shaft. The shaft itself is significantly thicker and 2 times stronger than the original. Due to its larger diameter, the integrated shaft must be used with the kit's custom, heavy-duty sun gear. Insufficient holding power is another area where many transmissions fall short, but installing thinner aftermarket steels and backing plates to increase clutch capacity isn't ideal. Those components increase clutch pack flex and heat build-up, making them the primary cause of repeat burn-up. To improve both performance and long-term reliability, the Smart-Tech's custom drum and piston hold an OE backing plate and seven OE frictions for 17 percent more clutch capacity than the six-friction stack-up. Sonnax Smart-Tech direct clutch drum and shaft kits feature: * One-piece design that eliminates weak point where drum splines strip and shafts break * Rugged shaft is 50 percent thicker and twice as strong as OE * Custom drum and piston deliver 17 percent more clutch capacity with optimum protection against burn-up * High-strength drum and shaft are precision-machined from hardened 8620 steel * Unique sun gear is precision-machined from 9310, heat-treated steel
