Caution: aFe recommends professional installation on our products. Allow time for your vehicle to cool down prior to installation. When working on or under your vehicle proceed with caution. Exhaust systems reach high temperatures and may cause serious burns. Wear protective safety equipment; eye goggles and gloves to ensure a safe installation.

Step 1: (Read instructions prior to installation) For faster removal and installation of exhaust a trained professional is recommended for this procedure.

Step 8: From the weld area of the catalytic converter where the pipe begins measure 2.0” down and mark a sharpie (This is from the catalytic converter weld to tangent). Refer to photo below.

Step 9: Now cut with a hack saw at your mark as straight as possible and deburr when complete.

Step 10: Re-install the left side catalytic converter.

Step 11: Using the supplied band clamp, slide the aFe loop over the straight section of the catalytic converter. But do not tighten.

Step 19: Your installation is now complete. It is recommended to re-tighten all exhaust components after 50 - 100 miles.

Note: aFe recommends that the tailpipe be at least 1/2”-1” away from any body panels to avoid heat related body damage. Tighten and secure.
