This G&G exhaust system gives the Yamaha T-Max a spicier 'look' and sound. Tight finished and with a deep, sporty sound. With a choice of two different endcaps, the damper can be adjusted to taste. I have been aimed for a smoother capital delivery, for more pleasure during daily use. The nearly two horsepower gain, measured without further adjustments to the engine, ensures a clear increase in the usable power. The kit will of course be supplied with all necessary mounting materials, a clear Dutch-language assembly instructions and the E-mark certificate.
