Signs of exhaust problems
A loud rumble, or a ticking noise at startup, often means a leak at a manifold, gasket or cracked pipe. A rattle from underneath can be a loose heat shield or broken internals in a converter or muffler. A rotten egg smell, poor acceleration or a converter efficiency code can point to a failing catalytic converter. Exhaust leaks are a safety issue, because carbon monoxide can enter the cabin, so fix them promptly rather than turning up the radio.
Fitment and emissions rules
Catalytic converters must match your engine and emissions certification. Vehicles certified to California standards, and those registered in states that follow them, generally need a CARB approved converter. Check the emissions label under your hood and the listing notes before ordering. On trucks, exhaust parts can change with cab style, bed length and wheelbase, so match those in the fitment table. Let the exhaust cool fully before working on it, and soak rusted bolts with penetrating oil the day before.
Exhaust questions
Do I need a CARB approved catalytic converter?
If you live in California, or your vehicle is certified to California emissions standards, you generally need a CARB approved converter with an Executive Order number. Several other states have similar rules. Check your state's requirements and the emissions label under your hood before you order.
What causes a catalytic converter to fail?
Converters usually fail because of an engine problem upstream. Misfires, oil burning and coolant leaks can overheat or coat the converter. Fix the root cause before installing a new one, or the replacement can fail the same way.
Is a ticking noise at startup an exhaust leak?
It often is. A leak at the exhaust manifold gasket or a cracked manifold tends to tick when cold and quiet down as the metal expands. Look for black soot marks around the manifold flange, and check for broken or loose manifold bolts and studs.
