Let’s be honest, having a loud noisy exhaust is no fun unless you are driving those Supercars that were designed to have massive exhaust power from the engine.
Are you also suffering from a loud exhaust? Don’t worry in this Article I will show you exactly how to quiet a car exhaust without losing performance.
Most new vehicles are now designed specifically to have a soundproofed exhaust, however, as the gets older or something happens the exhaust may start to exude a lot of noise and this may be more than just a loud engine so it is important you check your car if you experience any unusual noise.
If you are experiencing a loud exhaust that is very unusual, it is very likely your exhaust your exhaust pipe might be leaking somewhere, and if the exhaust is leaking whether from the engine, middle of the car or at the muffler, it can release carbon dioxide CO2 which is not good for your health.
How to soundproof an exhaust.
If you’re are looking for a solution on how to quiet a car exhaust without losing performance or power there are many ways you can go about solving that, I will show you the most effective ways that are proven to work and you can do them yourself.
Sound deadening a leaking car exhaust.
If you have identified any leaks in the exhaust you have to now see how big is the hole, smaller holes are easier and cheaper to repair, Larger holes are still easy to repair but slightly more expensive and if the exhaust is rusted you must replace the whole system.
Soundproofing small exhaust holes.
You will need an epoxy or patches. I recommend Permatex Repair Epoxy from Amazon (click here to check to see price). This is enough to cover small exhaust holes and it’s very affordable. To Use this follow these steps.
- Cut a slightly larger patch of the epoxy than the hole to make it overlap.
- Mix Up the epoxy and insert it into the exhaust leaking area(hole) and the edges.
- Use your hands to make sure the patch is stuck on the exhaust
- leave it for about 4 hours
- Test your car if the exhaust is still loud, you will need the special exhaust kit.
Method for Large exhaust Leaks.
for larger leaks, this may be slightly tedious but really effective and can be done easily and inexpensively if you pick the right material. You will need a patching exhaust kit and the best one is special exhaust patch kits from Amazon (check it here). A very affordable way to quiet an exhaust without losing performance and power and you can do it under $. But it is important to note that, the hole must be less than 3 inches for this to be effective.
In order to patch your car exhaust do the following:
- Clean the exhaust to get rid of any debris, dust or rust
- Cut the patch a little bit more than the hole to make it overlap
- Stick the patch and wait for a while before testing out.
This is really simple and should work if you have any hole in the exhaust causing it to make noise.
Using Car Exhaust Silencer Method.
This is one of the most effective ways to reduce any vehicle exhaust noise. I highly recommend this if your car is making a lot of noise on the muffler. One thing exhaust silencer does is, It makes it easier to soundproof an exhaust without going through a tedious process and wasting money on things that don’t simply work.
You can check out the Universal Exhaust Silencer Muffler (Here). To use this is very simple all you have to do is insert it in the exhaust pipe and you are ready to go, Plus its universal which means it works on any car.( check the price).
If the whole exhaust system is rusted, you might want to completely replace it, it’s much more cost-effective and the better way to go about silencing the exhaust noise without the car losing power.

- Park the car on a flat level surface
- Make sure the brake is applied( avoid the car moving)
- lay down next to the next to the car and check underneath if there are any leaks.
- For safety purposes, I recommend you ask someone to be inside the car to make sure brake is applied as you crawl to check the leakage underneath the car.
