How to Remove Yoshimura Baffles

Building a custom sports bike is all about increasing horsepower, but even if you already have a performance exhaust such as a Yoshimura, you can gain even more power by removing the baffles. It will be louder for sure, but by doing this you can easily buy two horsepower for not a whole lot of work, just an afternoon or so with power tools. It's one of the best kinds of custom motorcycle modifications--the free kind.

Things You'll Need

• Drill
• Metal drill bits
• Open-end wrench set
• Locknut
• Thread-locking compound
• Aluminum rivets
• Rivet gun

Instructions

1. Insert a metal drill bit into the drill that is approximately the diameter of the rivets located on the end cap of the Yoshimura muffler. Drill out each rivet using the drill, until the end cap can be completely removed from the exhaust.

2. Unbolt the baffle from the muffler, using an open-end wrench, then place the baffle to the side. Place thread-locking compound on the bolt that previously held the baffle in place, and tighten it through the baffle mounting hole with a locknut, so the muffler doesn't have a leak.

3. Place the end cap back on the muffler and insert a rivet into one of the holes where you drilled out a rivet in Step 1. Place the rivet gun onto the shank of the rivet and pull the trigger, tightening the rivet in place. Repeat this for all remaining rivets until the muffler is reassembled.
