How to replace the exhaust pipe on a 3.8L engine on Buick Regal?

The first step to replace the exhaust crossover pipe on a 3.8l engine includes removing the fuel injector sight shield followed by the throttle body air inlet duct before removing the air cleaner assembly. Begin by removing exhaust crossover heat shield nuts before taking away the heat shield and continuing with the exhaust crossover pipe bolts to separate its connection with the pipe and seal. The first step for installation should be to connect the exhaust crossover pipe seal onto the exhaust crossover pipe at its right exhaust manifold connection and then attach the exhaust crossover pipe. Secure the exhaust crossover pipe with 18 nm (13 ft. Lbs.) torque setting while you install the exhaust crossover heat shield and fix it using heat shield nuts that need to be tightened to 20 nm (15 ft. Lbs.). The completion of the installation requires the throttle body air inlet duct followed by careful reinstallation of the air cleaner assembly before finishing with the fuel injector sight shield.
