My bike came with a 4-1 exhaust, screw under the megaphone=baffles removable, how to?

Not sure what make it is came with bike. 1979 gs1000l. I removed the screw and tried to remove the baffles but the are either extremely stuck or not designed to be removed. But then, what's the point of the screw?

 

[Llamaguy]

They are just extremely stuck. At least mine came out. Pain in the but though.

Suggestions? I tried heating it up, clamping the exhaust (not chrome) with vise grips and tapping outward. Should I try soaking with PB or Sea Foam, then heating? I'd like to use a slide dent puller but can't figure out how to attach it.

Any chance of a pic? Most baffles in 4 into 1's are screwed at the front end and rivetted at the rear, the rivets are sometimes even ground off flat.
BTW you are aware that the baffle comes out to the rear?

I'll try and take a pic tommorrow. There is no rivet unless they ground it flat, and chromed over it. The screw is under the megaphone OUTLET about 1-1.5" from the end. and YES Dink I'm aware that the 3" outlet probably won't fit through the 4 1" tubes at the other end;-)

That screw may only hold the end cap on. youmay need to repack from the end.

What do you mean repack? If the end cap comes off does that mean the baffles might be removable. Any suggestion for trying to remove whatever might be removable?

I used to have a Kerker megaphone on my 1100 and it DID get stuck even after removing the screw under the meg. I would pull the the meg off and use a large wooden dowel inserted in the collector end and tap out the baffle with a mallet. This was how I did it on mine. You all takes your chances with yours.
