Catalytic converters are vehicle-specific parts. We recommend using a high quality new part, which is required by emissions control programs in many states.
A failing catalytic converter can cause a GMC Rally Wagon 1500 to fail emissions tests and the Check Engine Light to illuminate. The exhaust might have an unusual smell.
