Vance & Hines Shortshots are an aftermarket exhaust system for a variety of motorcycles made by Honda, Yamaha and Harley Davidson. Shortshots add a custom, straight-pipe appearance to the motorcycle while including street-legal mufflers and stock mountings for no-drill, no-weld installation. Shortshot pipes are featuree staggered, slash-cut ends and a 220-degree heat shield. Installation on the Harley Davidson FXR Super Glide is typical for a model powered by the popular Evolution series of engines.
Instructions
1. Remove the stock exhaust pipes.
2. Evaluate the stock exhaust gaskets and replace any that appear worn or defective.
3. Bolt the muffler mounting bracket, marked "278," to the transmission housing using the two 5/16-inch by 7/8-inch original equipment flange bolts, the 5/16-inch by 3/4-inch Allen bolt and 5/16-inch washers. Insert the two 5/16-inch by 7/8-inch original equipment flange bolts through the back of the mounting bracket before you tighten it to the transmission housing.
4. Spread the supplied tube clamp and slide it over the exhaust port end of the front head pipe.
5. Mount the OEM circlips and flanges on the front and rear Shortshot head pipes.
6. Slip one supplied dog bone-shaped nut plate beneath the bracket on the back of the front head pipe. Bolt the flat bracket (marked "279") to the head pipe with one supplied 5/16-inch by 5/8-inch flange bolt. Don't tighten yet.
7. Install the front head pipe using the original equipment nuts. Don't tighten yet.
8. Line up the tube clamp with the bracket just under the cam cover. Insert a 3/8-inch by 1-inch bolt with washer through the top of the tube clamp. Place another washer on the bolt and secure with a 3/8-inch lock nut.
9. Align the #279 bracket with the #278 muffler mounting bracket. Insert the 5/16-inch by 7/8-inch flange bolt into the dog bone nut plate on the rear of the front head pipe. Don't tighten yet.
10. Slide another dog bone-shaped nut plate beneath the bracket on the back of the rear head pipe.

Position the heat shields over the head pipes and turn the hose clamps so that the clamp screws are accessible. Tighten the hose clamps.
16. Loosen the baffle bolt on the back of the head pipes and adjust the baffles at the end of the pipes so that the endcaps are flush with the ends of the heat shield. Tighten the baffle bolt.
