Home > Dual Sport > Yamaha WR250X/R Parts Home > Used/Clearance Motorcycle Parts > Pro Circuit T-4 Exhaust NOTE ON USED PARTS: The used parts we sell are typcially parts that we pulled off one of our project bikes. They will include all parts for installation. We typically only have one available at this price. The Pro Circuit T-4 Exhaust System is designed to increase performance from bottom to top, making your Yamaha WR250R / WR250X perform better. The stainless steel and aluminum construction offer increased strength and durability; ideal for racing and off-road riding. This system is also tunable, meaning you can remove the spark arrestor screen turning it into a race tip for closed course racing; fasten the screen back on for off-road riding. The T-4 system for the WR250R / WR250X is the only one on the market that provides mounting points for the factory heat shields both on the header AND on the muffler itself. This allows you to attach your stock header heat shield to the Pro Circuit header, and also attach the stock muffler heat shield to the Pro Circuit muffler (See inset photo above). Fitment: 2008-2021 Yamaha WR250R / WR250X Sound: This exhaust is NOT one of the quieter ones. It is comparable in sound to the FMF PowerCore4 Exhaust so it is what I consider to be loud. We did confirm with Pro Circuit that they have a quiet insert that will fit it and knock a few decibels off the sound. Pro Circuit Part # on that is PC4012-0010 and it costs around $35.
