Mounting of Shelving Bracket
If you have all your tools ready, start with mounting a shelving bracket into a vise - called a mechanical screw apparatus. Make sure the bracket is firmly held and then catch the other end of the bracket with pliers and ready to bend it. Keep the vise at sturdy and solid surface so it does not move from its place while you bend the bracket. Mount the bracket up to an inch into the vise, not more than that.
By holding firmly the other end of the bracket bend it to a 90-degree angle. Do not push too hard, as the bracket can slip through the pliers and might slip out of the vise as well, and there can be a safety risk.
Drilling Hole in Bracket
After you bend the bracket to the 90-degree level, drill a hole in the end, which you have mounted in vise. That is where you will place the bracket with the motorcycle's exhaust pipe.
Attach Bracket With Pipe
After you have drilled a hole in the one end of the bracket, drill two holes at six inches distance from one end of the exhaust pipe towards exhaust exit. Attach the holed end of bracket with the pipe with a screw and tighten the screw with a screwdriver or an open-end wrench. Attach at least two brackets with one pipe.
Attach Brackets to Other Pipes
You should drill holes in all brackets to attach them with other exhaust pipes in the motorcycle, by attaching two brackets to one pipe each, and your motorcycle is ready with homemade baffles.
