Tools and Supplies You’ll need:

  • Door Weatherstripping
  • 3M Super 77 Spray Adhesive
  • Foam Weatherstripping
  • Scissors or Exacto Knife

Instructions: How to Make Exhaust Quieter Inside Car 

Step 1:

First, cut your foam weatherstripping into 9″ sections using scissors or an Exacto knife. This will make it easier to work with. Then, adhere the sections to the door frame.

Step 2:

The foam should be lined up with the edge of the door and overlap the hump in the middle. This hump is so that you can put pressure on it to make sure it’s completely closed when you shut your door. So, again, line up your foam with this so that it won’t pull the foam up when you shut your door.

Step 3:

Now, trace out where to cut the weatherstripping with a pen or pencil so that you’ll be able to get it around this hump in the middle of the door without too much trouble. Again, if you’re working with a rear-wheel-drive vehicle, the hump should be pretty close to one of the top corners.

Step 4:

Now it’s time to start adhering to your weatherstripping. Spray the door frame and the back of the weatherstripping lightly and wait 10 seconds for it to set up a little bit until it’s tacky. If it’s not, spray some more and wait a little longer. You want it somewhat sticky to adhere to the door frame but not wet enough for it to spill over onto the door itself when you press down on it.

Step 5:

Press down on your foam with one hand while spraying another section of weatherstripping with Super 77. Line up the foam and press down on it firmly to make sure it’s going to stick. Continue spraying, pressing, and tracing out your lines until you’ve reached a corner or end of a side of the door frame.

Step 6:

After you’ve traced out all of the weatherstrippings along one side of the door frame, place a strip of 3M weatherstripping in between the two sticky strips to hold them together. That way, when you continue tracing out on the other side, there won’t be any gaps or spaces where air can slip through. This will make it more difficult for sound to escape from inside of your car and will make it a bit quieter.

Step 7:

Do the same thing for all of the other sides of your door frame, and you should be done! It’s also a good idea to spray some on both sides of each strip where they meet so that there aren’t any points where air can sneak through.

Step 8:

Now, spray a section of door weatherstripping and put it on the car. Line up your foam so that it overlaps onto the car slightly, and trace out where to cut it so you can get around all of the curves in the body. Leave about 1/2″-3/4″ extra when cutting this one on each end. It makes it easier to work with, and you can always trim it later if you need to after adhering to it.

Tips to Maintain Your Car Exhaust:

1. Keep the car in a well-ventilated area. The exhaust is a boiling part of a car, and keeping it cool will prevent harm to you and your car.

2. Inspect your exhaust system for any leaks, holes, or defects in workmanship. These can cause noise from the flow of gases escaping from them when driving at high speeds.

3. Check your exhaust system for kinks, bends, and corrosion in the metal. Tighten any loose nuts or bolts to prevent further damage from vibration when driving.

4. Make sure that all necessary gaskets are in place. These can be very important in keeping heat and noise down to a minimum inside the car.

5. Check your exhaust system for cracks, holes, or missing heat shields. This can lead to rusting if moisture can get inside the car, where it will corrode metal.


There are many ways to make your car’s exhaust quieter. The key is finding the best solution for you and your specific vehicle, so be sure to research before making any changes! For example, the sound inside a car can be reduced by adding insulation to the floor, ceiling, and side panels.

If you are still concerned about the noise levels in your vehicle, try using an acoustic-absorbing fabric on top of carpeting or other materials that make it quieter for everyone who’s riding with you.
