Separating pipe from muffler (rusted tight)

[redbirds5]

Hi all,

I'm removing the pipe and muffler from my stock 01 MXZ600X to clean and polish up. They are rusted together at the joint and can't separate them; any suggestions? Should I try heating with torch or try penetrating fluid? I have the complete unit out from the chassis.
Thanks in advance,

I'd try penetrating fluid first. A couple days with a couple different applications. Heat WILL work but you never know, part of the muffler might stick around with the can

Good luck!

did that pipe not have a gasket and just slide in to can I think so and if I remember it came with a small tube of permatex to seal it with a new pipe so it could verry well be glued together silicon is a bitch

Yeah, the pipe just slides into the muffler and sealed with Ultra Copper hi-temp sealant.

take the springs off and start it!!!! It'll come loose.

There is always PB Blaster, 1 of my all time favorites. That and " starting it " like said above will give you heat & back pressure . a good combination I would think. I like the starting it idea.

this a shot in the dark....but we have used CO2 to freeze things that are stuck to break it loose.....i know the availability isn't very good.....just a thought

good advice...

Thanks everyone with the suggestions!
I've blasted the crap out of it with PB, still no luck. I can't start/run it, as I have my suspension out from underneath it (rebuilding the rear shock), but I'll give it a shot once she's back together.

Try heat then cool quickly(water). Do the heat-cool thing 2,3,4 times. I done this on things in the past and it has worked for me. The expansion and contraction cycles seem to help break things loose. If that doesn't work, explosives!
