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 St. Catharines? +
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.
