“These guys are experts in their field! They have all the parts on hand and can customize the exhaust system to fit as needed. I’m so lucky I found them after driving around the area to several shops that were too busy .Both visits of ours to this shop they put on pulse to what they were working on the bench with and attended to our vehicle. They calmly explained what was needed repaired it , went over the work and sent me on my way with a smile . Great father and son team I will recommend them to Al family and friends !!”

“I had a great experience at Globe Exhaust in Oshawa. The team was incredibly friendly and easy to deal with from start to finish. They took the time to explain everything clearly and made sure I felt comfortable with the work being done.

The pricing was very reasonable, especially considering the quality of service. It’s not always easy to find a shop that’s both trustworthy and affordable, but they really delivered on both.

I highly recommend Globe Exhaust to anyone looking for honest, reliable service. I’ll definitely be coming back in the future.”

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 Oshawa? +
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.
