I'd give 6 stars if it was possible. Haven't gone here yet but Chris, talking to you was like talking to my dad or family member. You explained everything about the catalytic converter that I need, the difference between CARB (California BS) and fed, and not to waste money on a catalytic converter just to have to have California stamp, even though it's a CA truck originally. Thank you and once I have the part, I will be there!!!
