Removal of Stock Component:

1. Remove the passenger side inner fender. See Figure 1.

Note: we also removed the Grille Assembly to prevent damage to it

during the removal or installation of the down pipe.

2. Remove the hex bolt securing the down pipe to the exhaust manifold.

Remove the sensor located just above the hex bolt. The V-Band clamp

connecting the front pipe to the down pipe can also be removed. Save

the hex bolt, sensor and V-band clamp for the installation.

See Figure 2.

3. The front pipe needs to be temporarily removed. Carefully disconnect

all sensors and loosen the four flange nuts on the rearward part of the

front pipe. The transmission cross-member will need to be temporarily

dropped to remove the front pipe. Remember to support the

transmission with a block or jack stand while doing the transmission

cross member is removal. See Figure 3.
