Removal of Stock System: 1. Apply a penetrating lubricant liberally to all exhaust fasteners, hangers and rubber insulators. Figure 1 2. For 2001-2005 vehicles use a 15mm socket or wrench and disconnect the factory exhaust system at the four bolt flange located behind the Catalytic Converter. Refer to Figure 1. If the vehicle is not equipped with a Catalytic Converter disconnect the four bolt flange located approximately under the passenger side seat.
4. Measure 20” across from the inside surface of the passenger side bed rail. Mark this location along the rail. This will be the approximate centerline of the Stack once installed. Refer to Figure 5. 5. Slide the Band Clamp (from Stack kit – purchased separately) over the Stack. Wedge the Stack Mounting Bracket between the Band Clamp and the Stack. Adjust to the bed rail height and tighten the Band Clamp slightly.
9. Measure from the Extension Pipe slip joint to the Mid Pipe. Mark and cut the shorter side of the Elbow to the required length so that it lines up with the Mid Pipe. Cut the vehicle’s exhaust system in a place where the Flex Pipe can be placed between the Mid Pipe and the Elbow. It may be necessary to cut the Elbow again as well as cut the Flex Pipe to ensure proper fit. Refer to Figure 9. Figure 9 10.
