How Do I Know if I Need to Replace My Exhaust?

Like other parts of your vehicle, even the best exhaust systems can eventually wear out or get damaged by environmental and road hazards. While you can sometimes perform a simple repair to fix a certain section, at other times, you might be better off swapping the whole system. Diagnosing exhaust problems quickly will help you maintain performance, efficiency and safety when you’re on the road or track. Conversely, failing to immediately address potential issues can lead to more expensive repairs later as well as health issues. Here are six signs of a bad exhaust that you should look out for as you drive.

1. Sounding Louder and/or Different

We know performance enthusiasts love a loud rumbling exhaust. However, if the exhaust is suddenly a lot louder than normal or is making odd noises, it could be a sign of trouble. The most likely causes of weird exhaust noise are loose pipes, faulty hangers and holes in the system.

2. Odor

A leaking exhaust can smell awful, so keep your nose on high alert. In particular, the smell of rotten eggs as you drive often indicates a catalytic converter problem. Bad gaskets can also lead to “hot engine” smells such as burning oil.

3. Fuel Efficiency and Performance Problems

Has your fuel mileage suddenly plummeted? A clogged or damaged exhaust may be the problem. If your engine is working harder than normal to release exhaust gases, it’s going to burn more fuel. Clogged pipes can also lead to lethargic acceleration, reduced power and other performance-related issues.

4. Vibrations

Are you feeling more vibrations than normal whether you’re driving or idling? Check the exhaust system. Problems that cause exhaust vibrations range from broken and cracked brackets to a clogged catalytic converter or busted muffler.

5. Rust

Vehicle exhausts are regularly exposed to water, heat and dirt. Exhausts made of lower quality steel will eventually rust out, leading to holes and weakened metal. Periodically give your exhaust a visual inspection for signs of rust.

6. Visible Smoke

In a well-working exhaust system, the gases are invisible once the car is warmed up. When you can easily see white, black or blue smoke long after starting the engine, it’s a sign of trouble, whether with the exhaust, the catalytic converter or the engine itself.

Exhaust Replacement Cost

Depending on the vehicle and whether you are getting an OEM or aftermarket system, a new exhaust can cost anywhere from $500 to $1,500. Premium exhaust systems will cost more upfront but last longer, often making them less expensive in the long run. A performance exhaust also has a higher initial cost but can offer benefits such as improved horsepower, better fuel economy and a customized sound.
