The exhaust is very basic; 3" pipe, Mandrel bends and a Dyno Max Ultra Flo. I like the Ultra Flo Welded Muffler because of its straight through design. I also have an exhaust made that goes straight out the back with a DynoMax Bullet on it. The police liked it so much the gave me a yellow certificate of gratitude. It turns out you can keep an exhaust like that but you have to pay the government extra for it!!! The Ultra Flo is quieter but is still very throaty. You've gotta have a good sound!
