Finally bit the bullet and bought a replacement section of exhaust for the merc. However the offending middle section is completely stuck.

I've tried smashing it off, pulling etc. Its a twin pipe setup so can't twist it with a pipe wrench. I thought about tieing a rope around it and a tree and pulling forward, but that could end badly.

Any ideas for getting it off other than get a bigger hammer?

Cheers, Tom.

edit:

would heating one section up and pouring cold water on the other bit work?
 
Is it a slip joint or a flange?

If its a slip joint then lots of swearing is involved, and try to break the crud seal if possible.

If its a flange then man up :p
 
When you mean slip joint, do you mean like a sleeve joint? I hate those!!

Chisel in between the two with some wd40 or similar. I gave up last time and let someone else do it! I doubt heat would work as you'd heat up the inner pipe too?

Those sleeve joints do my nut. The only way I've managed to part them is to get a chisel/ screwdriver in and prise the outer pipe open a little.
 
I had a devil of a job removing the CAT from my Jeep exhaust that needed replacing. I didn't have an angle grinder so did pretty much everything else to get it off - shouting at it, blunt hack saw, largest hammer I could find, shouting some more, catching my finger and bleeding a bit, smacking it against the house in disgust, shouting quite a bit more.

Came off in the end. :)

haha :)

Cheers for the advice guys, its a sleevey type one. normally i find twisting it gets them off nicely, but as its a twin pipe its a no go. I could angle grind it away, but then part of the pipe would still be in the other bit if you follow.

Gonna have a go on the chiselling method in a bit.

Thanks, Tom.
 
Slip joints can be loosened by repeatedly hitting them with a hammer all the way around and long their length to break the corrosion bond. However, if the clamp has been tightened sufficiently to crease the inner and outer pipes, this won't help much. In this case cut through the pipe at the end of the slip joint (making sure you don't cut through the part you want to keep!). If the remaining part you need to remove is on the outside, careful application of an angle grinder to slit it along it's length will sort it. If you need to remove a section of pipe from the inside, use a hammer chisel to collapse the pipe inwards.
 
Surely the two pipes are not welded to each other along the length of the car?

Cut the pipes on the section you are binning, get some grippy gloves and twist the remainder of the pipe off the sleeve?
 
If you can't grip with gloves and need more leverage just drill some holes through the pipe and poke a bar through, should help shift it!
 
argh this is getting on my nerves now. only got use of a 4.5 inch grinder or a 12 inch grinder! And because the car is lowered and I can only get it up on my small ramps, I can't really get at it properly to attack it with the grinder. Can get half way through, but not reach the rest.

So, I gave up on that and proceeded to beat the s*** out of it with a hammer, and a hammer and chisel to no avail.

Wish I did have a oxy acetylene torch, would be perfect.

Going to give up today and try again tomorrow.
