Failure in a Toyota Tundra's exhaust system can be caused by many different problems that shouldn't be ignored. A damaged exhaust system will not only affect your car's overall performance, it could also release harmful carcinogens into the atmosphere and cause serious health risks. That's why it's always best to take a few minutes to check your exhaust system when you're under the vehicle for an oil change or other component repairs. Take note of the most common problems encountered by an exhaust system and keep checking if your car is showing signs of a failing exhaust.
Noise coming from your Toyota Tundra's exhaust system definitely means trouble. Unwanted exhaust noise is usually a sign of a failing muffler or resonator replacement. You may also check the heat shields that protect your car's underside from the exhaust heat. The heat shields usually make rattling noises. However, if you notice deeper kind of rattles emanating from your exhaust, it could be coming from one of the silencers.
The most probable cause of an exhaust banging on the underside of your car is a tired or split rubber exhaust mount. When these mounts are worn and tired, they will end up swinging the exhaust around more than they should. Another thing to check when this problem occurs is the fitment of the exhaust. Make sure that the pipe is properly lined up with the trailing arm. Otherwise, it will result to an impaired clearance and the two will collide every time you hit a bump.
A leaking exhaust system can pose serious danger and should never be ignored. Carbon monoxide is an odorless and colorless gas that can be lethal when it seeps into the passenger compartment of your car with the windows rolled up. Always make sure to check your car for any form of corrosion as rust will eat metal. The most common spot for leaks are the welded joints. Regularly check these joints and keep them free from rust or other damages.
