Motorcycle exhaust baffle systems aid in reducing the noise from the exhaust pipes of the bike and also, it creates a form of back-pressure in the exhaust systems. Modifying a motorcycle’s exhaust system has become very popular these days, especially among the motorbike lovers. The drawback of baffles are that they increase noise pollution, and chances are, you may get a penalty for it. But if you still want to modify your exhaust system, it is not so difficult, and you can create homemade baffles with limited noise to your motorbike.

 

A baffle exhaust system is similar to any vehicle’s exhaust system, as it has a chamber that carries the fumes through the muffler into the air. As the gas is filtered through the muffler, a sound is not created. But is the muffler is removed, the exhausted gas passes through directly into the air with a loud noise when the bike is being driven.

 

Here is a guide on how you can make motorcycle baffles at home yourself, without adding noise to the bike:

 

Things needed

  • Drill
  • Pliers
  • Screws
  • Screwdriver
  • Vise
  • Shelving brackets
  • Hacksaw
  • C-clamps

 

Instructions

  1. Measure the inner diameter of the motorcycle tailpipe. Purchase a short length steel tubing with a smaller diameter than the inner diameter measurement you took of the tailpipe. The baffle tubing length will be 8-inches long.

 

  1. Secure the steel tube now in the bench vise, and then cut an 8-inch baffle with the hacksaw. Make three marks on the baffle: the first being 3-inches from one end; the second being 1.5-inches from the first mark; and the third being 3-inches from the first mark.

 

  1. You will then secure the end of the baffle in the bench vise vertically, along with the marks over the vise. Make crosscuts horizontally through the baffle at the marks with the hacksaw. Then, remove the baffle from the vise.

 

  1. Placing the baffle on the worktable with the cuts facing up, secure the baffle into place with a c-clamp.

 

  1. Place a cold chisel at the tip of the first cut, and strike it with a mallet. This will force the outer edge to move into the center of the baffle. Repeat this step over the other cuts so that baffle offsets are formed.

 

  1. Secure the baffle now into the vise. This should be done with a 3-inch end extending from the end of the vise. Add a small 1-inch drilled hole at the end of the baffle through the two walls of the baffle. This hole will be used for the steel bolt to hold the baffle to the tailpipe.

 

  1. Drill another hole through the tailpipe which will align the bolt holes into the baffle. Secure the baffle to the tailpipe now with a steel bolt.
