D & D bobcat 2 n 1, check their site and you tube it . Top tier performance , looks ,quality, and sound. The low cat is another option if you like the look better,.
I just got the Vance and Hines Pro Pipes. They are Very low toned and throaty. I am extremely pleased with the sound and power. I hope this didnt reach you too late. I live in MA pretty close to NH if you want to hear them.
