How to Fix a Broken Exhaust Pipe

Exhaust piping can break for a number of reasons. Rust, cracks, scrapes and holes can develop over the lifetime of the vehicle and require repair. In some instances, the exhaust may be too damaged to be repaired and may require replacement, but you might be able to repair some less severe kinds of damage using common hand tools. Start by inspecting the damage and assessing your repair options, then decide whether or not to seal the leak, replace the muffler, or take your vehicle in to a mechanic.Get more news about Muffler Pipe,you can vist our website!

Park the vehicle on a level surface. In order to repair an exhaust leak, you will need to jack the vehicle up to locate it. Always jack vehicles up on flat, level surfaces to ensure the jack won’t topple over as you lift the vehicle. It is also important to ensure the surface is sturdy enough to support the weight of the vehicle beneath the jack.
Wait for the exhaust to cool. You won’t be able to work on the exhaust pipe of your vehicle until it has cooled down for a while. The exhaust gas that travels through the exhaust piping is extremely hot while the engine is running and it could take hours for the metal to cool enough to touch.
Jack the vehicle up. Once the exhaust is cool enough to work on, slide a scissor or trolley jack under one of the vehicle’s rear jack points. Once in place, either lift and lower the handle (trolley jack) or turn the handle (scissor jack) to jack the car up.
Inspect the exhaust piping. If you aren’t able to easily identify the leak in the exhaust pipe, use the vantage point you gained jacking up the vehicle to visually inspect the piping and muffler. Look for signs of damage that may indicate a leak such a deep rusting, cracks, scrapes or holes.
Start the engine to help locate leaks. If you can’t find the leak in the exhaust pipe with a visual inspection, leave the vehicle jacked up and start the engine. With the engine running, you should be able to quickly and easily identify the source of the leak.
Determine the best way to repair the damage. If your exhaust pipe is severely rusted or has suffered extensive damage, it likely cannot be repaired and instead will need to be replaced. However, if the issue is a small leak or damaged muffler, you can patch the leak or replace the muffler using common hand tools.
Scrub around the hole with a steel toothed brush. You won’t be able to identify the size of the leak or effectively repair it until you remove all of the road grime, dirt and rust from the pipe around the hole. Use a steel toothed brush to scrub away the grime, being careful not to get any in your eyes.
Prepare the surface of the pipe with sandpaper. Sandpaper will remove any last bits of dirt and debris stuck to the pipe while scoring the steel surface to better stick when you apply the patch. Rub 80 or 100 grit sandpaper back and forth along the exhaust pipe around the leak you intend to seal.
Wipe acetone on the pipe around the leak. Acetone will ensure the metal is clean and free of anything that could interfere with the seal created by the exhaust tape or epoxy. Acetone is the primary ingredient in nail polish remover, so you may use nail polish remover for this step if you’d rather not purchase acetone strictly for this project.
