Removal Procedure

CAUTION: Always wear protective goggles and gloves when removing exhaust parts as falling rust and sharp edges from worn exhaust components could result in serious personal injury.

CAUTION: In order to avoid being burned, do not service the exhaust system while it is still hot. Service the system when it is cool.

An accumulation of dirt and corrosion may make removing exhaust components difficult. Applying a penetrating oil on the threads of the bolts may assist in the removal of these components.
