I made this Youtube video for a fellow club member in Switzerland and thought my NW budies would like to give a listen. If you have not heard these they are about 25% louder than stock, but much more throaty. They also have a 3" I.D. Vs. stock 2" which destroys HP. Ray Franscisco did a awsome job welding mine into place. Thanks again Ray!
