Verified Reviews for Exhaust System
★ ★ ★ ★ ★

“I was driving from winnipeg to Ottawa and drove into Thunderbay to get gas and as I turned into the gas station my car dipped into a deep pothole and scraped the bottom of my car. When I got out of the pothole some of the undercarriage was dragging on the ground. I quickly looked up “car repair near me” and Midas was identified as close. It was Friday afternoon. I called but they said they were all booked and recommended the name of another place. I was so close I just asked if I could just stop for them to take a look. Just to assess if the car would be safe to drive. They put it up on the hoist, identified the problem, made a temporary fix that could get me on my way safely. I was soooooo grateful. Everybody was kind and professional and in the end they even refused payment. If you need service for your car - get it at Midas!”

“Wow. Hats off to the whole team. We called in a pinch on a Saturday, 17 hours from home and Mike and the team worked to fit us in on a very busy day. Although they could not permanently fix our issue through no fault of their own, they provided outstanding service. Highly recommend! We picked up the truck during a hail storm.”

Failed flex pipes allowing exhaust leaks on front-wheel-drive vehicles

Exhaust System Tips

Have your exhaust system visually inspected at every oil change
If you smell exhaust fumes inside the cabin, get it fixed immediately—carbon monoxide is deadly
Address small rust spots before they become expensive full-section replacements
A rattling heat shield is an easy, inexpensive fix—don't ignore it
Keep your engine running properly to protect the catalytic converter from premature failure
Application of undercoating can help protect exhaust components from salt corrosion

Frequently Asked Questions

How much does a catalytic converter replacement cost in Thunder Bay? +
OEM catalytic converters range from $1,000-$3,000+ depending on the vehicle. Aftermarket units can cost $500-$1,500. The high precious metal content (platinum, palladium, rhodium) drives the cost.
Can I drive with a broken exhaust? +
While the vehicle may still run, driving with an exhaust leak is dangerous due to carbon monoxide exposure and may cause you to fail emissions testing. It should be repaired promptly.
How long does a muffler last? +
Mufflers in regions with harsh winters and heavy road salt typically last 5-8 years. In milder climates, stainless-steel mufflers can last the life of the vehicle.
Why is my catalytic converter failing? +
Common causes include engine misfires (unburnt fuel overheating it), excessive oil consumption, coolant leaks into combustion, or simply age and high mileage. Fixing the root engine issue prevents repeat failure.
