Even if you can't repair a faulty muffler yourself you can determine if the muffler is actually the problem. One of the first signs of a failing muffler is a change in the sound of your car when it starts and while it is running. The car will sound louder but you might not notice at first. If the muffler is not repaired the sound will definitely get louder and louder. In most towns sound pollution is an offense for which you will be written a ticket. That's only one reason to make sure your muffler gets fixed, and soon.

How to change a muffler on Chevy S-10?

First off, crawl under the truck and see if your present muffler is welded on or clamped on. If it's welded on you will need to get an exhaust cutting tool from like Autozone and cut the old muffler off BUT before you do, get your new muffler and measure how far the inlet neck is and outlet neck is on the new muffler and this will tell you how far to cut. You could hold the new muffler up to the exhasut and mark how far from the muffler you need to cut. This is assumign you are replacing the bad muffler with a new one of the same size. Now there is an inlet pipe and and out let pipe on the muffler. You will also need to have the right size clamps. Pu tone clamp on the exhaust pipe going to the engine, then push the exhaust pipe into the inlet end of the muffler and slide the clamp down and snug it up but do not tighten it. Put the other clamp on the exhaust pipe towrd the rear of the truck, push the exhasut ipe into the outlet end of the muffler and then slide the clamp down onto the joint and snug up. if everythign aligns right, then tighten the clamps. Sometimes if you overtighten the clamps you will have exhaust leaks. If you cannot get the joints to seal, you may need to get your system welded. If you exhaust is leak free then you are done. After a few hot and cold cycles you may just want to crawl back under and check the bolts on the clamps just in case they came loose from the heat and cold cycles.
