What Problems Can an Exhaust Leak Cause?

If any part of the pipe breaks, even a part that does not cause a leak, it can begin to hang under the vehicle. The dragging is not only a danger to you, but if it falls off of the vehicle it becomes a danger to the drivers around you.

  • Gas Smell

If you start to smell gas inside your car when you’re driving, this may be a sign of exhaust problems. It is usually caused when one of the exhaust pipes or tubes gets damaged and starts to leak. When that happens, the fumes from the gasoline escape through any place they can. Sometimes, that place is in the cabin of your car.
