Remove the 6 bolts and remove the transverse member.
Disconnect the electrical connectors from the alternator.
Remove the front exhaust pipe as follows:

Support the exhaust system at the catalytic converter with a jack or by suspending it on a piece of wire.
Disconnect the oxygen sensor electrical connector and remove the sensor using a sensor wrench.
Remove the 3 exhaust manifold flange nuts and remove the clamp from the hold-down bracket.
Remove the exhaust pipe-to-converter nuts and pry the rubber hangers from the mounting hooks. Remove the pipe.
