How to Install CGS Motorsports Aluminized Cat-Back Exhaust - Single Side Exit on your Sierra

1) Remove stock exhaust system

First start by removing the stock headpipe by unbolting the two bolt flange at the front.

Then slide the complete system carefully towards the rear off of the rubber hangers.

Remove the system from under the truck. Cutting may be required for removal for certain models.

2) Installing your catback exhaust system

Make sure that all exsting rubber Hangers are still in place. Install the flange end of the
new headpipe onto the stock pipe. Then insert the bracket from the headpipe into the rubber hanger. Now you will proceed to install Headpipe 02(part# 300-1096) by sliding it onto Headpipe 01. Proceed to install muffler onto headpipe 02 with the offset in the inlet and closest to the Driveshaft and the center in the outlet. Install the Tail pipe into the muffler and insert the brackets into the rubber hangers. Once the exhaust system is positioned and lined up correctly, install clamps at all connections. Install the stainless steel tip and tighten bolts.

3) Final checklist

Once completed, check to make sure all the clamps and bolts have been securely fastened. That's it, a simple install with a lot of results. Congratulations! You just installed more horsepower to your truck by allowing it to breathe easier with a CGS Catback Exhaust SyslemTM.
