what is the •Primary Tube Diameter (1.5 or 1.63) on the stock 2005 4.7L ... Thinking changing to performance exhaust headers?

Re: Headers!?!?
Not sure on the size BUT going overboard on the header tubes will kill your low speed torque, 1 1/2" tube size will be plenty, we use that size on our racecars to help them get off the corners better. Small is better on exhaust, going big will kill you on the street.
