How do they change the muffler when there isn't any clamp after the catalyst??

Some really amazing answers appear from people who you least expect. My 97 Dodge 1500 exhaust system is solid welded from end to end.
To cut the pipe, either a wheel cutter, die grinder, or a cutting torch can be used. The replacement mufflers have extra pipe on the ends which are expanded to fit the pipes and then welded in with a wire welder. Some shops may still use acetylene gas welders, which was used a long time before somebody invented
the wire welder.
Do you need a new muffler? Just ask the muffler shop man if you can stand back a ways and watch how he does it. My money is on one of the ways I mentioned.

it's very unlikely that your catalyst and your muffler are one unit. the catalyst usually has a flange that allows it to be bolted to the back half of the exhaust system. usually mufflers have the "U" type clamp holding the muffler to the middle section of exhaust piping.
in the event that the car has no clamps or flanges, it would mean that as some point someone has welded all the slip-over ends of the exhaust sections, if so, the exhaust shop will have to use a saw to cut the old piping out.
a good shop will weld in flanges or install the proper clamps when doing the repair.

The answer thus far, except the first, are good. The shop does use either a cutting torch or die grinder, depending on clearences.
Once done, they will need to lenghten the extension pipe with another section to make up for loss due to cutting. Otherwise the tail stock will not match OEM. Most of the time it's better to replace the unit from the cat back.
As for 'welding' it on............how well do you think they will get completely around the pipe, without setting the carpet on fire from the heat next to the floor pan, while attempting to blaze the upper side that you can't see to 'weld'?

shops are required via utilising the EPA to maintain the eradicated catalytic converter for 15 days after the fix and take care of all documentation of the fix for 6 months. they are in violation of federal law in the event that they do no longer. After 15 days they are able to do away with it and you will possibly be able to retrieve it after that element located on law in fairly some states that require the fix save to grant you all asked replaced aspects. the best exception is aspects that have a center value even nonetheless ought to you adjust to pay the middle value they are going to grant you the ingredient.

WHEN CUTTING THEY CAN EITHER USE A TORCH TO CUT IT OF OR A DIE GRIND CUT OFF WHEEL. TO WELD IT THEY USE A MIG WELDER.
