Like all Flowmaster products, the benefits include improved throttle response, power and engine efficiency. Designed for an easy fit, these headers include gaskets and necessary hardware for easy installation. Note: this product has been granted a California Air Resources Board (CARB) exemption, an E.O. number, or is a direct or consolidated replacement part. It is 50-state legal, per the application guide for 2002-2013 4.8L/5.3L and 2007-2013 6.0L/6.2L applications. CARB EO# D-698-20.
