Your Spare Tire & Heat Shield will need to be removed for installation. (FACTORY RUBBER HANGER GROMMETS WILL BE RE-USED, USE WD-40 TO AID IN REMOVAL.).

- Install muffler onto head pipe #A 1-1/2” to 2” with the louvers facing towards the converter. Use a jack stand to support the muffler. Use clamp #H to secure the muffler to the head pipe. Do not tighten.
- Install metal hangers #K using Bolt Kit #J. We will Re-use the middle support hanger grommet from the stock exhaust for this bracket.
- Install the Over Axle Assy. #C into the muffler at least 1-1/2” to 2”. #C needs to be installed from the back of the car where the Spare Tire Sits. Use clamp #H to secure the pipe to the muffler. Do not tighten. Insert hangers into the rubber grommet.
- Install the Over Axle (B) #D onto the PS output of the First Over Axle Pipe then install Over Axle (C). Use clamps #G to secure pipe. Do not tighten.
