Never ignore exhaust smells inside the cabin; drive with windows cracked and have the leak fixed immediately to prevent carbon monoxide exposure

If a heat shield is rattling, a mechanic can often secure it in 15 minutes with a stainless band clamp

Fix engine misfires or oil leaks promptly so unburned fuel does not melt your catalytic converter honeycomb

Frequently Asked Questions

How much does exhaust or muffler repair cost in Portugal Cove-St. Philip's? +

In Portugal Cove-St. Philip's, welding a broken hanger, flange, or flex pipe typically costs $120 to $300. Replacing a muffler runs $220 to $500, while catalytic converter replacements range from $600 to $2,200+ depending on the vehicle.

Can a rusted exhaust flange or flex pipe be welded instead of replacing the whole pipe? +

Yes. As long as the surrounding pipe still has solid metal, an exhaust shop can cut out the rusted flange joint or braided flex section and weld in a new sleeve or flex pipe for a fraction of the cost of a full assembly.

Why did my P0420 catalytic converter Check Engine light come on? +

Code P0420 means the downstream oxygen sensor sees the catalytic converter storing less oxygen than expected. Before replacing an expensive converter, have a shop check for small exhaust leaks near the O2 sensor or a lazy sensor first.

Is it safe to drive with a loud exhaust leak? +

Aside from noise bylaws, an exhaust leak ahead of the rear axle allows odourless carbon monoxide gas to rise into the passenger cabin when stopped at traffic lights. Have exhaust leaks repaired promptly.
