How do you remove baffle from Yoshimura exhaust

Most baffles can be un-screwed from the rear; some others from the inside after removing the exhaust.

Step 1 - Remove Exhaust Remove the whole exhaust from the bike.
Step 2 - Drill Out the Baffle With a ½" hole saw and a handheld drill, insert them into a hole in the exhaust's outlet. The handheld drill will not go further inside the exhaust once you hit the baffle. Drill through the 1st baffle and then each remaining baffle until they are are drilled. Remove the baffle pieces.
Step 3 - Replace Exhaust Reinstall back the exhaust system onto your bike.

go to the mechanic and look in manual of bike good luck

Instructions

1. Take Down
   • 1 Park the motorcycle on the kickstand or center stand and allow the exhaust pipes to cool completely.
     
   • 2 Refer to your Suzuki service manual and organize the metric tools needed to remove the baffle. On newer models, it may be necessary to remove the tailpipe section to modify the baffle. On older models, you may be directed to remove a bolt that secures the baffle in the tailpipe.
     
   • Follow the procedure given in the manual and remove the tailpipe section or slide-in baffle using the appropriate tools. Save any brackets or bolts. Place the tailpipe or baffle on a workbench.
     
   Tailpipe Baffles
   • 4 Hold one end the tailpipe up to a light and look inside the other end. Depending on the baffle, you may see very little light or none at all. Modifying the baffle is a matter of opening up areas in the baffle.
     
   • 5 Chuck a 1/4-inch drill bit in an electric drill. Use a bit extension if necessary to reach deep into the tailpipe with the drill bit.
     
   • 6 Place the tailpipe on a workbench. Use a towel or rags to prevent scratching the finish. Insert the tip of the drill bit into the tailpipe and drill a 1/4-inch hole in the baffle.
     
   • 7 Hold the tailpipe up to the light again. Determine the number of additional holes you want based on the purpose of the modification. Drill additional holes in the baffle if needed.
     
   • 8 Stand the tailpipe on end and tap it on the workbench to clear the debris from drilling out of the baffle. Make sure all debris is cleared out before reinstalling the tailpipe on the motorcycle.
     
   Slide-In Baffles
   • 9 Secure the outer end of the baffle in a bench vise with the baffle extending to one side. The outer end has the threaded hole where the bolt was removed to take the baffle out of the exhaust pipe.
     
   • 10 Measure the length of the baffle and divide it by four. You modify a slide-in baffle by cutting off a one-quarter section at a time using a hacksaw. Mark the baffle at the one-quarter point and cut the first section off the end.
     
   • 11 Reinstall the baffle in the exhaust pipe using the saved bolt and the metric tool.
     Start the motorcycle and determine if the modification produced the desired result.
     
   • 12 Allow the exhaust pipe to cool completely before removing the baffle for further modification. Most likely, cutting one or two quarter sections will give you the result you want. Avoid cutting too much off the baffle, or it will be useless.

If thebaffle has not been removed before it may well be stuck in with the silicone sealent that is used to seal the exhaust, you should be able to twist the baffle to losen it, it is not unusual for the baffle to become tight, when eventualy you remove it clean the seating area and use a copper anti seize grease when replacing it, as suggested by most exhaust m,fctrs

Dont do it ... motorcycles are delicately balanced for best operation. Not to mention removing the baffle will annoy those of us who will have to listen to you roar past.
