Description:
Designed to meet California emissions standards, as well of those of other CARB-regulated states.. Magnaflow California Universal Catalytic Converter - 2.25in..
Keep the check engine light off with MagnaFlow California Grade CARB Compliant Universal Catalytic Converter 5421205. The Universal design allows the part to fit a wide array of vehicles (cutting and welding required), and the stainless steel construction of this spun body catalytic converter is highly resistant to corrosion. The single laser fusion weld of the spun body greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.
