However it is recommended you drop the transmission if you have a stock clutch and need to upgrade (5-speeds). The bolts holding them on may seize or be extremely hard to remove w/o pulling the tranny. Remove the brake master cylinder and battery. New 02 sensors are also recommended. If using old sensors, most of the time the pre-cat bung will come out with the sensor. The bung needs to be removed first from the sensor and then you can reuse the old sensor with your downpipes.
