separating pipes
Is there a good way to separate a muffler from the exhaust pipe without destroying them? Exhaust is off the car and not rusted. I would like to keep from destroying either piece but the muffler is the part i really want to save.

Is the pipe welded to the muffler?
I did mine last winter but wasn't trying to save the pipe, just the muffler. The best method I found was using an electric grinder with a cutoff wheel I cut around the circumfrence of the muffler flange on the inside seam of the weld. Then I usded a big plumbers wrench and turned the pipe out of the remaining muffler flange. A chain type pipe cutter would probably be easier than the grinding method I used. If they aren't welded and you want to save both muffler and pipe I would wrap some masking tape around the pipe and use a plumbers wrench to turn the pipe out of the muffler flange. I did this just recently when fitting a new tail pipe on the muffler but couldn't remove by hand. It worked well and didn't nick up the pipe.

There is tool called EZ Pull.

Use a torch to heat up the pipe or the muffler. The steel when red hot will separate and even work out any crimp from the clamp.

I worked in a muffler shop, and turned wrenches for over 50 years, this method works very well to save the pipe and muffler. The Summit tool is on back order to 5/10/21 by their site. |

I have the same issue. Saw this one on ebay...The Summit item didn't show a price? Maybe because it's backordered? https://www.ebay.com/p/1173749459

I remember putting a clamp on the pipe and striking that with a hammer to slide it out of the muffler.

The nice thing about using the torch is as you wobble the pipe out from the inside of the connection you can enlarge the outer pipe on the connection for re-use by stretching it. As has already been mentioned you can also work out the dents in the outer pipe made by the clamps as you disassemble the joint.
Heat wrenches are the most used tool in an exhaust shop, by far. |
