There are a few factors.. A big one depends on your exhaust system period, it may just be a loud set up that was installed, aftermarket performance system, or something of that nature. If it is stock, or just a normal exhuast system, then you have a leak. Even if you can see it, doesnt mean there isn't one. Holes will usually wear around clanps, and supports. any place that constantly rubs during vibration. You can often find these by starting the engine, and crawling underneath the car and listening. Another way is by applying smoke, or spraying soapy water (only works until pipes get hot, then shut off, and wait for cool down, continue where you left off) and looking for the mix to bubble. Another common area of leaks, are in the actual muffle body it self, the larger diameter part of your exhaust right before the tail pipe. Alot of times mufflers after age will develope holes around seams and edges.

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.
