Planning a summer road trip? Whether you’re driving across the state or hitting the open highway for days at a time, your vehicle’s exhaust system plays a bigger role than you might think. It does more than just direct fumes out the back of your car—it also affects your fuel efficiency, engine performance, and overall safety.
Before you load up the trunk and hit the gas, here’s what to check on your exhaust system to make sure your trip goes off without a hitch.
1. Listen for Unusual Noises
A healthy exhaust system should be fairly quiet. If you hear rumbling, hissing, or a loud growl from under your car, it could be a sign of:
- A hole or crack in the muffler or pipes
- A leaking exhaust manifold
- A broken or loose exhaust hanger
These issues can lead to reduced engine performance, louder-than-normal driving, and even exhaust fumes leaking into the cabin—definitely not something you want during a long trip.
2. Look for Rust or Damage
Salt from winter roads, moisture, and age can cause rust to form on your exhaust pipes, muffler, or catalytic converter. Light surface rust is usually fine, but deep rust or visible holes can lead to serious problems.
- Check under your vehicle for rust spots, corrosion, or flaking metal.
- If anything looks weak or damaged, have it checked by a technician.
- Don’t forget to check the tailpipe—damage here can affect the entire system’s function.
3. Watch for Drops in Fuel Efficiency or Power
If your vehicle suddenly feels sluggish or you’re making more stops at the gas pump, your exhaust system might be the reason. A clogged catalytic converter or a leak can interfere with your engine’s ability to breathe properly.
- Poor acceleration, rough idling, or engine misfires can all be symptoms.
- These problems usually get worse over time, especially under heavy loads like road trip gear or highway driving.
4. Make Sure the Check Engine Light Isn’t On
Many exhaust issues, especially with the oxygen sensors or catalytic converter, will trigger the check engine light. Don’t ignore it—get a diagnostic scan before your trip to make sure everything’s in order.
- Faulty sensors can cause your engine to run rich or lean, affecting performance and emissions.
- A pre-trip scan can help catch small issues before they turn into big ones on the road.
5. Inspect the Exhaust Mounts and Hangers
These brackets and rubber mounts keep your exhaust system firmly in place. If one breaks or comes loose, your exhaust could sag, rattle, or even drag under the car.
- Listen for banging or clunking sounds when driving over bumps.
- A technician can quickly check the hangers and replace any that are worn or damaged.
Final Thoughts
Your exhaust system might not be something you think about often, but it plays a key role in your car’s performance, fuel efficiency, and safety—especially on long summer drives. Before your next road trip, have your exhaust system inspected by a professional. It’s a simple step that can save you from unexpected breakdowns and keep your ride quiet, clean, and running strong all the way to your destination.
