FAQs— Volkswagen Muffler
- Is it okay to modify my exhaust system to alter the sound that the muffler gives off?
It depends on where you live. Some states have specific emissions regulations and set limits on the level of sound the vehicle can produce. So before you make any aftermarket enhancements to your vehicle’s exhaust system, check first with your local department of motor vehicles if it is allowed. By doing so, you will also know the legal modifications that you can do to your ride.
- I’ve decided to weld my Volkswagen muffler for a more secure installation. Any pre-installation tips that could help make my DIY project faster and easier?
It is important that you clean the exhaust area where the muffler will be attached. The muffler itself should also be clean before installation. Surface rust should be sanded off. It’s also a must to compare first the muffler you are welding to the exhaust pipe as they need to be either similar in size or with just a slight overlap. When you gather all the tools you need for the job, make sure you also have proper welding safety gear, particularly goggles, welding mask, and an apron that’s fire-proof.
- Can you suggest a temporary fix for the hole in my muffler?
Use a muffler patch tape to cover the hole temporarily. All you have to do is wrap the tape around the muffler, exactly over the hole. Make a number of passes around the muffler, making sure each pass overlaps the other by approximately 1/2 inch. After cutting off the excess tape, smooth up the patch using your fingers. Don’t worry about curing time because the patch will just cure once the exhaust system warms up.
- How can I get rid of carbon buildup in my Volkswagen muffler?
You can eliminate it using carburetor cleaner spray or combustion chamber cleaner and a wire brush. All you have to do is to spray liberal amount of the cleaner at the exhaust tip as well as the inside of the muffler. Allow the cleaner to work first for several minutes before scrubbing the inside of the tailpipe using the wire brush. Catch the carbon particles coming out of the tailpipe by placing a tray underneath the opening. The carbon buildup can’t be eliminated in one procedure, so repeat it 2 or 3 times. It’s also a good idea to do this regularly to avoid further carbon buildup.
- After taking a peek underneath my ride, I noticed that my muffler is already filthy. Is it okay if I take it off my Volks and wash it? What’s the proper way to clean it?
Yes. It’s actually better if you take it off your ride so you can clean and lightly wash the entire muffler surface well. After removing it from your VW, wipe loose dirt off with a lint-free cloth. Grease can be removed by lightly washing the surface of the muffler with water and dishwashing soap. Lightly scrub tough stains with a scrubbing pad. Just be careful not to scratch the metal. After washing, wipe it dry and then polish it to restore its shiny finish. Make sure to use the right polish for your muffler’s finish, though.
- The muffler of my car is already corroded, but the exhaust pipes still look fine. Can I reuse the pipes?
Yes, as long as they are still in good condition, you can reuse your exhaust pipes; just be careful when separating them from the muffler so as not to damage them. If the exhaust pipes are clamped to the muffler, it will be easy for you to separate them. In case you damaged the pipe when detaching it from the muffler, you can use an adapter fitting to reuse it and reconnect it to the new muffler.
- I am fixing my muffler and want to make sure that it won’t rattle afterwards. How can I achieve that?
A rattle-free muffler is possible. All you have to do is to make sure that the pipes are positioned properly before tightening the clamps. If you doubt the pipe’s alignment, wiggle it around until it is aligned well and does not touch any suspension component or the underside of your ride. Once the pipes are properly aligned, that’s the time to mount the new pipe clamps and tighten them firmly.
