“What an assume guy, he was so honest I would highly recommend him. For something I thought might’ve cost me $400 to fix with something that turned out to be minor and only charged me $20.
Who does that these days?
I will be highly recommending him not only for a great personality. but awesome work, very happy customer !
Thanks again!!!

“This location on Tautan is the best.
They only tell you what parts and services you need. My brakes where squealing the guy said and showed me the front rotor and pads needed replacing. Then showed me the back which had some groves but not bad and are ok for now. Most places would have said to replace all the brakes. Also the guys are super nice and friendly.”

Catalytic converter deterioration from engine misfires and rich-running conditions
Broken or deteriorated exhaust hangers allowing pipes to sag and vibrate
Exhaust manifold cracks from repeated heat cycling
Impact damage from road debris or bottoming out over obstacles
Failed flex pipes allowing exhaust leaks on front-wheel-drive vehicles

Signs Your Exhaust System Needs Repair

Loud rumbling or roaring sound from under the vehicle
Check Engine light related to catalytic converter efficiency codes
Rattling noise from a loose or failing heat shield
Strong exhaust fumes smell inside or around the vehicle
Decreased fuel efficiency and reduced engine performance

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.
