On certain Ford trucks and vans, the original equipment studs connecting the catalytic converter to the exhaust manifold flange can typically rust and break, and removal can be difficult, but Dorman has an OE FIX. Their exhaust flange repair kits offer a cost-effective, faster, and much simpler way to securely reconnect the converter and flange using ordinary hand tools, and without drilling, heating, or welding. Dorman exhaust manifold flange repair kits contain a pair of sturdy stainless steel brackets designed to fit over the broken stud sections on the manifold flange, and feature an integrated threaded stud that slides through the catalytic converter mounting holes. Just push the threaded end of each bracket through the catalytic converter mounting holes, place the contoured side of each bracket against the exhaust flange and around the headless broken studs of the exhaust flange, and secure the connection with the included stainless steel nuts. Make flange repairs without the high cost and labor of replacing the complete pipe. Select a Dorman kit for your OE FIX.

Summit Racing™ is proud to offer Ecoboost turbo manifolds for the 3.5L Ecoboost engines. The factory manifolds are known for warping, cracking, and then leaking when used under heavy loads. Our upgraded stainless manifolds are much heavier than the lightweight factory versions and they flow better which improves exhaust flow and lowers back pressure, allowing the turbos to spool quicker. Since they must be replaced you might as well gain some power and mileage. Check out these features below: * Cast in high-strength and corrosion-resistant CF8 (304) stainless steel * Extra thick flanges have higher resistance to warpage and cracking * Individual runner into collector design with over 60 percent more internal volume * Port matched outlet with integrated gasket anti-extrusion ring provides 37 percent increase in outlet flow area * Additional bolt hole provides three studs for each exhaust port * Direct bolt on with no additional modifications or parts required
