How to Make Motorcycle Baffles

Motorcycle exhaust systems function relatively the same as a car's. The exhaust pipe exits the combustion chamber, carries the exhaust gas through a muffler, then expels the gas into the atmosphere. Because some riders like their bikes to sound louder or to rev faster, they remove the mufflers. This leaves nothing for the exhaust gases to pass through and makes the bike loud. If you want to boost performance without increasing decibels, you can add your own homemade baffles to a straight-pipe set-up and deaden the noise just enough.

Things You'll Need

• Small shelving brackets Drill Small metal screws Pliers Vise

Instructions

1. Mount 1 inch of a shelving bracket into a vise and grab the other end with pliers.

2. Bend the shelving bracket 90 degrees and drill a hole in the end that was in the vise.

3. Drill two holes in the exhaust pipe 6 inches from the end. Slide the bracket into the exhaust pipe and use the metal screws to attach it. Use two brackets per pipe.

4. Repeat steps 1-3 for all exhaust pipes on the bike.

Tips & Warnings

• Most bikes, though not all, have one or two exhaust pipes.
