Motorcycle exhaust baffles lower buzz and fabricate back-pressure.
Motorcycle exhaust baffles serve two purposes: Contract the Clamour from wide-open exhaust pipes and actualize back-pressure in the exhaust action. Limiting clamor emission is not exclusive thoughtful, nevertheless is required by principle in many localities. Those with enlightenment of motorcycle engines extremely catch a definite vastness of back-pressure is needed to avoid wick a inventory engine. Baffles are not compound pieces of Accoutrement. Common baffles consist of steel tubing with a series of offsets that combine to lower bewailing and generate that compulsory back-pressure. You can accomplish motorcycle exhaust baffles in your workshop with shop tools.
Instructions
1. Degree the inside width of the motorcycle tailpipe. Get a short length of steel tubing that has an absent width 1/16-inch less than the inside calibre of the tailpipe. The overall length of the steel tubing depends on the numeral of baffles you intend to constitute. Accepted baffles are 8 inches lenghty.
2. Secure the steel tubing in a bench vice and intersect an 8inch baffle using a hacksaw. Objective the baffle for three offsets using a felt-tip marker. The basic indemnify is 3 inches from one cusp. The moment is 1 1/2-inch from the head objective. The third countervail is 3 inches from the first mark.
3. Secure one end of the baffle vertically in the bench vise with the offset marks above the vise. Make horizontal crosscuts halfway through the baffle at each of your marks with a hacksaw. Reposition the baffle in the vise if necessary as you go. Remove the baffle from the vise.
4. Place the baffle on the workbench with the hacksaw cuts facing up. Secure the baffle in place using one or more c-clamps.
5. Position the tip of a cold chisel at the first hacksaw cut. Strike the cold chisel with a mallet to force the outer edge of the cut into the center of the baffle. Repeat this at the remaining hacksaw cuts to create the baffle offsets.
6. Secure the baffle in the vice with the 3-inch end of the baffle extending from one end of the vise.7. Mark and drill a 3/16-inch hole through the tailpipe that aligns with the bolt holes in the baffle. Once installed, the outside end of the baffle should be flush with the end of the tailpipe.
Chuck a 3/16-inch drill bit in an electric drill. Drill a hole 1-inch from the end of the baffle and through both walls of the baffle. The hole is used for a stainless steel bolt that holds the baffle in the tailpipe. Secure the baffle in the tailpipe with a 1/4-inch diameter stainless steel bolt, lock washer and nut. The length of the bolt depends on the outside diameter of the tailpipe.
