I'll try to give you a short version of the instructions I have.
Disconn. batt., Disconn. hego sensor from cat (retain), remove cats and crossover as unit. PASS. SIDE: Remove starter, Remove exhaust manifold nuts and lower front stud, Support engine with jack and remove motor mount bolts, Raise engine 1.5", check engine clears nearby parts, remove exhaust manifold and gasket then remove remaining studs, install new manifold and gasket. Install bolts, torque to 15-20 ft-lbs, lower engine, TIGHTEN MOTOR MOUNT BOLTS, reinstall starter.
DRIVER SIDE: Disconnect EGR tube at exhaust manifold., loosen bolt on steering shaft collar at the rack, separate collar from rack by prying shaft backward and place shaft out of the way, remove dipstick tube, remove exhaust manifold nuts, remove exhaust manifold and gasket and then remove studs, install studs in exit flange of manifold, install new manifold and gasket, the dipstick tube needs to be reinstalled between the exhaust flange and the engine block prior to the installation of the manifold, install provided bolts and torque to 15-20 ft-lbs., reinstall the steering shaft and tighten the bolt on the collar, attach EGR tube to manifold, reinstall cat assembly, reconnect hego sensors, reconnect battery, start engine, test for leaks---go get many beers!
Good Luck
