INSTALLATION INSTRUCTIONS #617301

CAREFULLY READ INSTRUCTIONS BEFORE STARTING INSTALLATION

When installing this exhaust system make sure to use proper safety precautions. Use jack stands when working under the vehicle, set parking brake, block tires and use safety glasses and gloves. Allow exhaust to cool before attempting installation. Severe injury or burns could occur if safety measures are not taken.

1. Disconnect the negative battery cable before removal of 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.


2. To remove the stock exhaust, unbolt band clamp located just behind your factory muffler.
Disengage the welded hangers using WD-40 from the OEM rubber grommets. Do not damage or remove the rubber grommets as you will reuse them to mount your new system.


3. Install head pipe #A onto your existing stock front pipe and attach with clamp #E. Insert welded hanger into rubber grommet. Do not tighten.


4. Install muffler onto head pipe #A 1½”-2” with the louvers facing towards the inlet. Use a jack stand to support the muffler. Use clamp#E to secure the muffler to the headpipe. Do not tighten. Muffler inlet is looking into the louvers.


5a. Next, install the exit pipe #C.


5b. Use clamp #E to secure to the exit pipe. Do not tighten.


6. Install stainless steel tip. Clamp down. When you have everything in place, firmly tighten all bolts and clamps down securely. Use stainless steel cleaner and a Scotch Brite pad weekly to prevent tip from discoloration. Inspect all fasteners after 25-50 miles of operation and re-tighten as necessary.
