Yamaha YZF-R1 with G.P.R Exhaust System

With G.P.R. you get it all – the quality, the look, and the performance of the best and most expensive racing pipes available. From concept to final welding and packaging each G.P.R. exhaust is the product of over 40 years of experience at the state-of-the-art manufacturing facility in Milan, Italy

G.P.R. uses the latest computer aided design techniques, then extensively track and dyno tests each prototype exhaust to find the best combination of horsepower and torque. Once the best design is found, production exhausts are hand fitted and hand welded one by one to match the prototype.

G.P.R. racing exhausts feature beautiful hand TIG welding, super strong and lightweight 304 alloy stainless thin wall construction, true tapered headpipes, and gorgeous silencers that are light and enhance the power with a deep tone that is unmistakable. It’s difficult to overstate the quality, construction, and performance of G.P.R. pipes – they are that good. Our own dyno has shown bikes gaining as much as 8 HP without any fuel adjustments! Expect another 2-4 HP with proper carb jetting or FI mapping adjustments.
