After further inspection, you see a small hole. It also sounds too good to be true. Does muffler tape really work? The problem is internal. The good news is that even when your muffler has a visible hole, it may not mean you need to replace your entire exhaust system.
Specialized auto repair shops with the ability to repair and replace individual components of an exhaust system can save you a lot in unbudgeted repairs. If your car is louder than usual when you crank it up or accelerate, if you smell fumes coming from your tailpipe while driving or if you notice a change in your gas mileage, these can all be signs of a muffler problem.
Having been bitten by the car bug at a young age, I spent my formative years surrounded by Studebakers at car shows across Quebec and the northeastern United States. Over ten years of racing, restoring, and obsessing over automobiles lead me to balance science writing and automotive journalism full time. I currently contribute as an editor to several online and print automotive publications, and I also write and consult for the pharmaceutical and medical device industry.

If rust penetrates through all the way through a pipe, it will result in a leak. Cracks in the piping are another common cause of exhaust leaks. Start the vehicle to help locate leaks. If you are unable to readily identify the source of the leak with a visual inspection, have a friend start the vehicle.
From beneath the car or truck you should be able to spot the leak as puffs of exhaust smoke escapes from it. Keep your hands away from any moving parts. Make sure the vehicle is in park for automatic transmissions or is in neutral with the wheels chocked standard transmissions before starting it. Assess the extent and type of damage. Depending on the type of damage you identify on your exhaust piping, your repair options may vary.
If the exhaust piping is covered in extensive rust, that entire component of the exhaust may need to be replaced by a professional. Small scrapes or holes can be addressed without cutting out portions of the exhaust. Larger holes will need a piece of aluminum in conjunction with an epoxy to seal.
Method 2. Scrub the area surrounding the leak with a steel toothed brush. Because the exhaust is located on the underside of the vehicle, it often gets caked with mud, dirt and rust. Once you locate the leak, use a steel toothed brush to scrub the area surrounding it.
Most repairs will not stick or seal if done over dirt and grime. Make sure to wear eye protection while scrubbing the area to prevent debris from getting in your eyes. Use sandpaper to prepare the surface of the pipe. Once you have scraped off most of the dirt and grime, take a piece of fine grit sandpaper and use it to scrub the portion of the pipe you need to repair.
Sandpaper will remove the last bits of dirt as well as creating tiny micro abrasions in the metal to help the tape or epoxy adhere to it. Roughing up the surface of the metal will create a stronger bond for the patch. Wipe the surface down with acetone. Once you have brushed and sanded the pipe around the leak, wipe the area down with acetone to clean it and help the exhaust epoxy bond to the metal.
Acetone is the primary ingredient in nail polish remover, so using nail polish remover will work well for this purpose. You can purchase acetone in the cleaning chemicals section of many retail stores, or nail polish remover in the health and beauty sections. Determine if the hole is small enough to be sealed without a patch. Small cracks or pinholes can be sealed using just epoxy or exhaust tape, but larger holes will need a patch. If the leak is a thin crack or small hole, you can proceed without purchasing or making a patch to help.
If the hole is larger, you will need a patch as well as epoxy. Wrap the exhaust tape around the pipe. If you are using exhaust repair tape, wrap it all the way around the pipe, covering the exhaust leak with at least two layers of tape. Make sure to wrap the tape around the pipe for a few inches to either side of the leak as well. Different kinds of exhaust repair tape will require different application methods, so be sure to read the instructions thoroughly before you begin.
Other forms of exhaust repair tape needs to be wet before applying. You can purchase exhaust repair tape at most auto parts stores. Mix the epoxy together and apply it to the leak. If you are using epoxy to seal the leak, mix the two parts together using a wooden dowel. Once the two parts are mixed, it will begin to cure immediately, so apply it to the leak quickly. Dab the epoxy over the leak, then use the wooden dowel to spread it around the area.
Leave a thick layer of epoxy over and around the leak. Different types of epoxy have different curing rates, so read the instructions on the package to know how long to allow it to sit before driving the vehicle. Method 3. A catalytic converter is a device on a vehicle the reduces the toxicity of emissions from the engine. You can use steel putty to seal any hole or crack in the catalytic converter.
This will form a permanent seal that will last a long time. You can buy the putty at any auto store. Far better to apply additonal layers , if need be for build up, as soon as the first layer has "set up" to where it's stable.
Most mufflers would deal with temperatures which range between and degrees Fahrenheit. Because of the heat intensity being produced by the emission system of the engine, most of the exhaust systems are indeed built to handle an excess of almost degrees. At room temperature, J-B Weld sets in hours to a dark grey color. A full cure is reached in hours. This Nickson Muffler Cement - Part set hours. Full cure after 24 hours. It cures by the evaporation of water and further cures with heat.
Noise is often the most obvious sign of a hole in the muffler. Cars with a hole in the muffler will make loud, rumbling noises, with the noises getting louder as the hole gets bigger and the muffler falls further into disrepair. Permatex Muffler and Tailpipe Sealer is the best sealant to use on exhaust joints.
