Exhaust System and Muffler Repair

When your Engine Breathes Easy, so can you

A properly maintained exhaust system does more than just reduce engine noise. A properly functioning exhaust system also reduces emissions coming from your vehicle and increases your vehicle’s fuel efficiency. Your exhaust system includes components such as the exhaust manifold, catalytic converter, exhaust pipe and muffler, each of which needs to be kept in good order to keep your vehicle running properly.

Symptoms to look out for:

  • Check engine light is on
  • Overly noisy engine
  • Decreased power and acceleration
  • Decreased fuel efficiency
  • Smell of exhaust or gasoline in your vehicle
  • Vehicle backfiring

Do you believe you may be having problems with your muffler, emissions or any part of your exhaust system?

As part of Roy Foss Thornhill’s Exhaust System Maintenance Service, our GM Certified Service Experts inspect every component of your exhaust system and can perform any necessary repairs or replace any components, including the exhaust manifold, exhaust pipe, catalytic converter and muffler.
