Best Answer:Hi, This headers has no oxygen sensors provision. This part is legal for sale and use on Emissions Controlled Vehicles, in all 50 states, when used in accordance with the manufacturers application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number. <a href="https://www.holley.com/products/exhaust/headers_and_exhaust_manifolds/all_headers/parts/91837FLT" target="_blank">https://www.holley.com/products/exhaust/headers_and_exhaust_manifolds/all_headers/parts/91837FLT</a>
