This thread has an oddly disgusting name.

Anyway, I am trying to install a new shock in my '06 DRZ400SM, and I have run into a problem. I have to remove the back half of the exhaust system, which is currently an aftermarket Yoshimura system. The head pipe and the mid pipe fit together, sans fasteners, right above the right footpeg. This junction was held together by sliding a male end into a female end, and then bolting all of the other mounts up.

The effin thing WILL NOT come apart now. I have removed all of the mounts, and actually went as far as to unbolt the front section of the system from the motor, and remove the pipe from the rear section, and then beat the back section with a hammer on one of the mounting brackets. I have it moving, but it is being stubborn.

I was thinking of trying to heat the junction, but I dont know if that would help? I assume that if I heat where the pipes meet, they will both expand and it wont help.

Any suggestions are appreciated. Except for lighting the bike on fire, I already thought of that.

Heat the outer just a little. Don't soak the thing enough so both pipes expand together. It'll work.

Cool, thanks.

I have a heat gun, the kind you use to pull stickers off stuff. It gets pretty hot.....do you think that would be enough, or should I hit up the hardware store for one of those propane torches?

heat gun will do it.

Soak a rag in cold water, wrap it around the pipe section with the male end, heat the pipe section with the female end. The wet rag will act as a heat sink, hopefully keeping the male section from expanding as rapidly as the female section while you heat it with a torch.

Use LOTS of lube.

Brilliant! if that doesn't work, you'll have to cut it to bits...

Only if you were in need of reassurance of your manliness like me. But the short answer is yes.

I so should have asked this question a year ago.

Would have saved my neighbors hearing me cursing and banging all night when I changed my exhaust.

Keep your sex life out of this...
