Exhaust Pipe Baffle

 Shop Exhaust Pipe Baffle

Motorcycles are outfitted with an exhaust pipe baffle to regulate the sound that the engine produces when running. In some states, installation of this component is extremely important especially when the rider frequently drives his motorcycle early mornings or during the wee hours of the night. Not only does it control the noise produced by the motorcycle, but the baffle also creates a little bit of back pressure, which is a good thing for your motorcycle's engine.

But, no matter how efficient your exhaust baffle is, age and constant use can take their toll on it. Before you know it, the decibel level of your exhaust noise will suddenly increase. When this happens, your motorcycle will suddenly become a nuisance and may start calling the attention of local law enforcers. If you don't want to end up getting a ticket, you'd better replace your damaged exhaust pipe baffle as soon as possible.

Exhaust baffle removal and installation is fairly straightforward and can be done even by a novice DIYer. Here's a step-by-step guide to help you out:

How to Remove Baffles from an Exhaust Pipe:

What you'll need:

  • Drill
  • Metal drill bits

Step 1: Park your motorcycle in a solid, level ground and set the kickstand or put on the parking brake.

Step 2: Position yourself in front of the exhaust pipe and find the rivets around its perimeter. These rivets hold the cover in place on the end of the exhaust pipe. You need to remove them to gain access to the exhaust pipe baffle.

Step 3: With your drill and metal drill bits, bore out the heads of the rivets and with your hands, pull out the cover from the exhaust pipe.

Step 4: Carefully pull the baffle from the center all the way out of the exhaust pipe.

How to Install a New Exhaust Baffle in Place

The process of installation will depend on whether or not the exhaust pipe comes with a baffle mounting hole. If you're installing a replacement baffle, then your exhaust pipe surely has mounting holes. But, if you're installing the baffle as add-on because your motorcycle isn't equipped with one, then you'll have to make mounting holes first.

What you'll need:

  • Permanent marker
  • Drill
  • Metal drill bits
  • New baffle
  • Vise
  • 1/4-inch self-tapping bolts

Step 1: To determine where the mounting holes should be, hold the exhaust pipe baffle on the underside of the pipe, with the baffle's end adjacent to the end of the pipe and its cone part pointing forward.

Step 2: Using a permanent marker, mark the pipe right where the topmost part of the baffle's cone is resting.

Step 3: Drill a 1/4-inch hole at the mark that you've made on the bottom of the pipe and make a 3/16-inch pilot hole in the cone part of the baffle.

Step 4: Slide the exhaust pipe baffle into the pipe, making sure you align the hole you've made in the pipe with the one you've drilled in the baffle.

Step 5: Get the 1/4-inch, self-tapping bolt and insert it into the holes. Tighten it firmly to secure the baffle cone tight against the pipe and keep it from rattling due to engine vibration.

Note: If your motorcycle's pipe already has mounting holes, proceed directly to steps 4 and 5.
