FAQs— Dodge Muffler
- During inspection, I noticed a hole in my Dodge muffler. Can you suggest a temporary fix until I can bring my Dodge to a muffler shop?
This problem can be serious, and it may even require a replacement. But if you want a quick fix so you can make the muffler work well until you have the time and money to take your ride to a professional mechanic, you can weld a piece of metal over the hole. If you don’t have a welding machine, you can still cover the hole with a piece of metal and hold it in place using a baling wire. Keep in mind that these are just quick fixes; the best solution is still to take your Dodge to someone specializing in muffler repair. This may not come cheap, but that’s the best way to have the problem fixed.
- What's the most common cause of rattling in the muffler? I’ve been hearing some lately, and I'm not sure where to start looking.
The rattling sound can be caused by a loose heat shield. To repair this, you have to safely support your car with jack stands, get under your ride, and find the muffler. You won’t easily see the heat shield as it is situated in between the muffler and gas tank, and it just appears as a curved piece of metal secured in place by bolts. Hold the heat shield and wiggle it. (Note: if you’ve pulled off from a drive, wait until the vehicle cools down before working.) If the bolts move as you wiggle the heat shield, then they are loose and may need to be retightened. Just tighten the bolts and try to wiggle the shield again. If you don’t notice any movement, then you can now put your car back to ground level.
- I've been hearing a rattle around the muffler area and traced it inside the Dodge muffler. It seems like there's debris or something inside it. I tried to remove the muffler and shake it to see if debris will come out, but the rattling is still there. Any ideas?
You can try to cut open your Dodge muffler and just weld it back after. If the muffler is already old, it’s a good idea to just replace it with a new one. Also check the catalytic converter as the debris causing the rattling sound might have originated there.
- I have heard of cases of muffler explosion. How serious are these? What can cause a muffler to explode?
There are several muffler problems that could lead to explosion. The usual cause is excessive backpressure, which is due to clogging. When there’s clog, gas builds up on the muffler, unable to flow towards the tip and therefore causing explosion. Running rich and flooding the car are other probable causes. It can also be because of rusting of the muffler's internal components. You should also be mindful of your catalytic converter as it can get damaged and may back up into the muffler, causing a clog and leading to explosion.
- How can I protect my Dodge muffler from rust?
One way to prevent rust from eating away at the muffler material is to regularly clean the muffler using a mild cleaner or a degreaser. You may need to raise the rear of your Dodge to gain access to the muffler. Hose off any dirt and spray on the cleaner. Alternatively, you can dip a rag in a bucket of water and use it to wipe dirt away from the muffler. Also pay attention to the area around the muffler welds and the clamps that are holding the exhaust together. After cleaning, dry the muffler with a rag. You can also spray paint the muffler for added protection.
- How beneficial is a dual exhaust system?
A dual exhaust system, as its name implies, includes two mufflers to help improve the engine’s efficiency and the vehicle’s overall performance by simply filtering and directing more exhaust gases away from the engine. Since there are two mufflers working at the same time, the engine doesn’t need to work too hard to push exhaust gases out. You must, however, be particular with the exhaust construction and make sure it really contains two mufflers because some manufacturers split the exhaust pipe into two after the muffler to make it seem like there are two tailpipes but, in fact, contains only one muffler.
- I’m planning to purchase a new Dodge muffler, but I can’t choose between a stainless steel and an aluminum muffler. How do I know which type I need?
Your choice should depend on where you reside and what you really want from your Dodge muffler. Those who live in places with high moisture or road salt can go for a stainless steel muffler. People who reside in drier lands can go for an aluminized steel type. If you aren’t very particular with corrosion resistance, the muffler material shouldn’t matter much to you. If you put much weight on the part’s durability, stainless steel mufflers are more durable than other muffler materials. In fact, they can last up to 10 years.
Quick Guide to Fix Your Dodge Muffler
Repairing a faulty Dodge muffler is manageable but may be time-consuming if done alone. It is better to ask for an extra pair of hands to make this task faster and easier. Here are some easy steps to help you restore your vehicle's exhaust system in top condition.
Difficulty level: Moderate
Things you'll need:
- Jack stands
- SAE or metric wrenches
- Electric reciprocating saw or hacksaw
- Penetrating oil
- New exhaust pipe
- Exhaust clamps
- Exhaust hanger
- Ball-peen hammer
- Cold chisel
- Safety glasses
- Work gloves
Step 1:On level ground, park your Dodge vehicle. Using a jack and jack stands, raise the vehicle as high as possible at all four wheels. Securely position the jack stands under the frame of each wheel.
Step 2:Before starting to repair the faulty Dodge muffler, make sure your vehicle's exhaust system has been cooled down. When it is cool already, go under the vehicle with a flashlight to determine the area or part of the exhaust pipe that has been damaged. For most vehicles, there are two parts of pipe. The first part is located between the muffler and catalytic converter while the second part is between the muffler and exit point. When you have identified the part that is broken or has been damaged, get the required part in a reputable automotive shop or repair supplier. You can also get new exhaust clamps and holder as it is easier to replace them than to use the old ones.
Step 3:Organize and lay out all the parts, tools, and the new exhaust pipe in a clean work space.
Step 4:Using a SAE or metric wrenches, carefully take out the old exhaust clamps.Start removing these clamps by gently twisting and pulling the old pipe section to release it from your Dodge muffler. Take out the exhaust hangers from the pipe. Start removing the pipe out from the vehicle. You may use an electric reciprocating saw or hacksaw.
Step 5:Mount in the new exhaust pipe in the reverse order of the removal steps. Carefully position the new pipe into its place under the vehicle. Initially reattach it loosely to the exhaust hangers. Slide the new exhaust clamps over the new pipe. Place the new pipe into position over the old Dodge muffler. Move the exhaust clamps into their appropriate positions and securely tighten the nuts. Go back and make sure to tighten properly the exhaust hangers.
Step 6:Inspect your handiwork. Ensure all connections, bolts, and nuts are tight. Double check the exhaust pipe to ensure that it is secured firmly under the vehicle.
Step 7:Lower your Dodge back to the ground and start your engine. Observe for sounds of exhaust leaks.
For easier removal of bolted connections, you can apply penetrating oil to these parts. In addition, you may use a ball-peen hammer or a cold chisel to release the end of the exhaust pipe that slides over the muffler. Ask for another set of hands to help you position the new exhaust pipe under the vehicle.
