2021 Nissan Rogue Sport Rear View

Why is my exhaust so loud all of a sudden? That’s a question you may be asking if you’ve experienced that loud, obnoxious exhaust rattle from a muffler or exhaust pipe that needs to be repaired or replaced. The service center at Gunter Nissan of Martinsville is here to help you keep your car running in top shape on the Roanoke roads, so we’ve put together a guide below about how to troubleshoot and temporarily fix a loud exhaust.

Why is My Exhaust So Loud All of a Sudden?

If you got here by typing “Why is my exhaust so loud all of a sudden?” into Google, it’s because you want to know what’s causing that loud exhaust noise. So, here are the most common causes of an exhaust rattle:

  • A crack in the exhaust pipe or muffler – This can happen if the car hits something underneath or just from rust or regular wear and tear. You may need to crawl under the car to see this.
  • A leak in the exhaust system – To detect if this is the case, lay next to your car while it is running in park and check for any fluid dripping along your exhaust system.
  • A rusty muffler or exhaust pipe – Exterior rust will not cause the system to make a noise at first. But rust will work its way through the muffler or pipe over time causing cracks and holes.

How to Temporarily Fix a Loud Exhaust

We say “temporarily” fix a loud exhaust because if there are failures in your exhaust system, it will eventually need to be replaced. This is the average Martinsville driver’s skill set and will usually need to be done by a professional. So, schedule an appointment with our service center when you hear that exhaust rattle. Here are some ways to fix a loud exhaust temporarily:

  • Apply epoxy sealer or sealant to smaller holes. Note: Never put sealer or anything else inside a hole in the exhaust. Apply to the outside only.
  • Cover larger holes with repair patches.
  • Repair a cracked, rusted exhaust with bandages and exhaust paste.
  • Tighten any screws or bolts that have come loose.
