Can't get baffle out of yoshimura

Just bought a 2006 with full yoshimura exhaust. Not loud enough. I took out the bolt holding the baffle in no problem, but I can't get the baffle out. I have tried:
thumbs
allen wrench hooked in the screw hole and pulling
allen wrench and hammer up from the hole of the screw
socket wrench handle wiggling around inside
socket wrench handle at an angle to try to pull it out
monkey wrench gripped on the lip (and now my baffle is kind of torn up looking)

It can wiggle a little bit, but just won't come out.

Any pointers? Anyone know how long the baffle is? Maybe I need something to hook to the back of it and pull??

I have already pulled so hard that the bike has come back towards me, which just seems wrong. I don't want to put so much strain on the mounting.

Why not? Is it not really meant to come out or something?

I would use a set of needle nose pliars. FWIW, here's what the baffle on one of my TRC carbon slip ons looks like from my RC51; might help to give you a reference point for what you're working with (YMMV, of course):


-'11 Graphite Black CBR 1000RR (sold)
-'02 Silver & Black CBR 954RR
-'06 Black/Metallic Gray RC-51
-'08 Pearl Orange CBR 600RR (sold)

That's pretty much what the rs5 one looks like.
Might be able to use the spring puller over the end. Be careful not to damage the inside of the can.
Other than that; wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap, wiggle, tap....... Then repeat....... LOL!!

Do you think there might be more than one screw? I removed the one at the back end of the exhaust that was clearly attached to the baffle. I don't see where another one would be.

^ Doubt it, the vast majority of exhaust silencers/baffles are usually held in place with one small hex/allen screw.

Chances are good that you probably have some carbon build up making the silencer "stick" to the inside of the canister. You're gonna need to use the proper tool for the job or get some stronger muscles. Use a "twisting" force to help break it loose.

Or, try removing the canister so you can put it on your work bench to get better leverage (vice clamps?) when removing the silencer/baffle from the canister.

Thanks guys. I am going to try the flapper mod first and see how that goes. When I am in higher RPMs I think the exhaust sounds fine. But when cruising on the highway around 4-4.5k I am silent and that is the part I am trying to fix.

hit the inside of it with a good healthy spray of real "non-environmentally friendly" brake cleaner...
that will break loose any carbon-gunk holding the thing together.
