Our high-performance catalytic converter for Chevy Impala optimizes your exhaust system and reduces the amount of toxic pollutants you put into the air. Engine performance suffers when oil or antifreeze contaminates your catalyzing mechanisms. Because of this, your fuel consumption will increase and you're at risk of failing your next emissions test. Impala catalytic converters from AutoZone eliminate pressure and trapped exhaust, optimizing your fuel economy. Order today for Same Day Store Pickup.
