STANDS WHEN UNDER TRUCK, SET PARKING BRAKE, BLOCK TIRES AND USE SAFETY GLASSES.
DO NOT WORK WITH HOT PIPES!!!
1. Disconnect the negative battery cable before removal of the OEM Exhaust. This will allow
the computer to reset and recognize the new exhaust. Lay out the exhaust on the floor so it
looks like the drawing and compare parts with manual. Remove the factory exhaust by cutting
behind the factory muffler. Once the tail pipe has been removed un-bolt the muffler and head
pipe at the clamp located in front of the factory muffler.Use wd-40 or another type of
penetrating oil to remove the rubber grommets. Do not damage these they will be re used.
