Headers replace the cast-iron exhaust manifolds with tubular pipes. This is Stainless Works' long-tube kit in 304 stainless with 1-7/8 inch primaries, 3-inch merge collectors and catalytic converters built in. "Factory Connect" means it is designed to bolt straight to your stock exhaust.
why this one — Choose this version if you are keeping the factory exhaust, since it is built to mate to it and costs $190 less than the Performance Connect kit that needs a Stainless Works exhaust behind it. It is listed for the 5.3L only, carries a lifetime warranty and is made in the USA, with no published horsepower figure. Long tubes are a shop install and want a tune.
No horsepower/torque figure stated on the listing checked.
"This product is NOT CARB legal and CAN NOT ship to California" (stated verbatim on listing).
No published gain figure for this part, and nothing here is a guarantee. Price is a list price and can lag the retailer; confirm at checkout. See our affiliate disclosure.
