hey guys started to do exhaust donuts last night am everything went good until it was time to get the can or silencer out. Told the bolt out of the clamp and just can't get them to seperate. Any ideas?
 

dead blow hamer and get mad at it. sounds funny i know but i think thats what the service manual says.
 
I have found that if you stand behind the sled and grab the two silencer outlet pipes, then rigorously lift/twist/turn/pull the silencer backward, eventually it loosens up and pulls out. A dead blow hammer does help get things started for sure. Spray some PB blaster or similar on the joint ahead of time to get some lube penetrated into the mesh gaskets etc. This process works best if you do it before loosening off the Y-pipes from the tunnel mount and headers.
Also, care should be taken when re-installing the silencer into the two Y-pipes, very easy to mangle the round mesh gaskets, I usually polish the Y-pipes well and apply a film of grease to the pipe and gaskets in order for them to slide together easier. The mesh gaskets are compressed and don't relax if at all, so the fit when re-installing is very close, and the gaskets can fold or peel over easily if not aligned well.
The tubes of the silencer are serrated where the mesh gaskets go, to allow the band clamps to tighten down on the mesh gaskets. When replacing damaged or worn gaskets, I work these serrated ends over a mandrel I turned up on the lathe to expand the joint again, this makes installing both the new gaskets and the silencer over the Y-pipes a breeze.
Cheers
 
Well tried what you guys said and nothing. Still stuck together then was gonna pull the whole exhaust out as one and work on it on the bench but couldn't get 1 bolt out of the clamp. Turning into kinda a pain
 
Oh ya, mine wooped my a**. Finally took a cut off wheel and did away with their design, used new gaskets and for $10. Had muffler shop make 2 10deg off set pipes, getting old makes working upside down worse. This was a breeze, took new gaskets so shop could stretch ends perfect size.

I drill the y pipe bracket rivets and leave the y pipes attached to the muffler. Pull it back, do your donuts then rivet the bracket back on the tunnel. Works like a charm.
 
I tried this the other day and ended up doing what I needed without taking it off cause it wouldn't budge. Does reefing on the silencer mess anything up by the motor?

I leave it all attached to the motor and tunnel at the donuts or it will flex to much when you rock it back and forth to pull it off.
