This is the only performance exhaust in the world that is designed specifically for the SG250. This exhaust is Made in America using all stainless steel construction. It is very easy to install and it produces 2+horsepower just from bolting it on. This is not a straight through open exhaust, this is a hybrid using traditional fiberglass in 2/3 of the muffler and redirection chambers in the last 1/3 of the muffler. This combination provides very good peak horsepower numbers while offering a pleasant deep tone. The exhaust is quieter and more powerful than other performance exhausts. Pair this exhaust with the Stage 3 performance package and a 28mm Nibbi carburetor for unbelievable performance gains.
