The Dorman catalytic converters you’ll find at AutoAnything are designed for a precise fit, but differ from one another in that one complies with Federal EPA emissions standards – and therefore, is not legal for use in California – while the other is legal in all 50 states. Quality-manufactured and built to last, each one reduces the amount of harmful gases released into the atmosphere, and comes to you backed by an unbeatable 1-Year, Lower Price Guarantee.
