Causes for Loud Car Exhaust

The reason why your car exhaust is louder than others is the car exhaust itself. That is your car could be sounding off because your car is either too old or too powerful.

The sports car which we see on the TV are loud and makes a loud annoying noise but besides this point, the reason they are loud is that they are more powerful than the other cars which makes them loud.

The more powerful a car is the more noise it will produce. However, some of the old cars have a loud exhaust which is due to rust and you hear the pipes jangling against the bottom of the car as they are loose of course these cars also have other things lost inside them. Although you can eliminate the noise by placing some of the sound-deadening materials.

If you’re the owner of a supercar and truck then luckily there are similar solutions to make car exhaust quieter. Let’s discuss some of the ways to make a car exhaust quieter.

How To Make Car Exhaust Quitter

Let’s discuss some of the ways to make car exhaust quitter one by one I will be sharing the ways.

1. Find The Leaks

The primary thing you need to do is find out the leaks which produce unpleasant sounds. All you need to do is find a firm surface and level to a height that will allow you to work safely beneath the car.

Search for concrete or blacktop. Don’t risk your health with grass surface or something unsteady which will put your health at risk. Let your vehicle cool down. Exhaust pipes take several hours to cool down before being able to work on them.

Since it has reached a level of high temperature so it might take a while to cool down. Jack it up and it will be ready to inspect the leaks. Inspect the area and find the leaking spots. Search for weak spots rust, holes, and cracks.

If your vehicle is the lower one then the damage might come from bumping into the holes. If you still can’t find the leaks then turn your vehicle. You will need a friend who can look for the car exhaust smoke while the car is running.

When you finally find the leaking spots then you directly need to fix it with the approaches depending on the size of the hole and cracks and if you cannot fix it by yourself then you need a hand professional.

2. Fix The Leaks

The first thing about fixing leaks is to understand that there are some leaks that are easily fixed and some needs professional to fix. There are small leaks and larger leaks.

Small Leaks

If you find that there is not much rust and the leaks are small then luckily they are easy to fix. This kind of leak can be easily fixed with exhaust tape.

This is quite easy to stop the annoying noise of the car exhaust and make the car exhaust quitter effectively.

Large Leaks

When it comes to larger leaks they will cause unbearable noise. you will find them directly and fixing them might take a bit more time. You can use a patch combined with epoxy in order to seal the leaks.

The first thing is you need to figure out big the patch must be. You can buy these patch kits at any auto parts store. As an alternative solution, you can use an aluminum can which is one of the cheapest ways.

Once you find your sealing material, you need to scrub and clean the booth, exhaust pipe, and sealing material. If you’re going with aluminum and once you’re done with cleaning measure the size you need to seal.

Cut the aluminum so that there are at least several inches more than a hole actually in order to cover it fully. After you’re done with cutting and cleaning your material is ready to attach together.

Apply the epoxy on both sealing material and exhaust in order to stick it even harder. Press the sealing material to the leaking hole and make sure you fix it without any leaks.

Put more epoxy in order to seal it even better. Use epoxy over the whole patch. You’re almost done with making car exhaust quiet. Now all you need to do is make sure the patch is secure and steady.

If you don’t secure it the patch will simply feel off during a ride so it’s a better option to stiff them with hose clamps. After following this step I have made the car exhaust quieter.

3. Replace Muffler With Quiet Muffler

After doing these steps if you still feel that the car exhaust is making noise then you need to replace the existing one with the new muffler which is quieter.

You need to pay close attention to this one and not all models will fit your car. The best option is to go to the local store of auto parts near you and ask for help. You need to get the specific year and the model of your car in order to get the fit muffler.

However, after finding the muffler which is fitted for your car than you need to replace it with the older one. Most of the time the muffler is covered in rust.

Use W-40 to loosen the bolts. You need several applications before removing the muffler. In case there are muffler clamps then you can use a wrench to loosen it up.

Once you did then slide the muffler and the exhaust apart. After removing it use a rust penetrant to secure and clean the area around the exhaust.

After a few minutes, you will be able to pull the muffler forward so that you can slip these two parts. Once you remove the old one then you will be able to place the new quiet muffler in its position.

Apply exhaust sealant to make sure there are no leaks. This whole procedure may sound confusing but it isn’t. you need to follow these simple steps to make your car exhaust quitter without losing performance.
