Step 1: (Read Instructions prior to installation). It may be helpful to lubricate all the factory isolation rubber mounts, before
taking off stock exhaust and also before installing aFe exhaust. Always use a jack or stand for support when installing or
uninstalling any exhaust system.
Step 2: Begin by removing your stock exhaust from the rear of your truck working your way forward. Remove the factory muffler
assembly and mid-pipe/resonator. Take caution not to damage the factory isolation mounts as they will be reused.
NOTE: It may be easier to unbolt the muffler hanger brackets from the frame than to disconnect the factory isolation mounts.
Step 3: Remove the factory ball clamp from the mid-pipe/resonator.
Step 4: For faster installation spread the pieces of the exhaust alongside of your vehicle, according to the diagram shown. It is
recommended to not fully tighten any of the clamps until the entire system has been fully installed.
Step 5: Place the factory ball clamp removed in Step 3 onto the muffler assembly.
Step 6: Install the muffler assembly onto the factory y-pipe and loosely tighten the factory ball clamp.
Step 7: Place a 2-1/2" band clamp over the rear side of muffler assembly. Slide the mid-pipe into muffler and slip the hanger into
rubber isolation mounts
NOTE: For 4 door applications use provided extension pipe first.
NOTE: If the factory muffler hanger brackets were removed from the frames at Step 2 then reinstall the drivers-side, and
passenger side hanger bracket and isolators before Step 8.
Step 8: Place a 2-1/2" band clamp over the rear side of the mid-pipe. Slide the rear muffler assembly into the mid-pipe and slip
the hangers into the rubber isolation mounts.
Step 9: For 49-48075-B and 49-48075-P, install the exhaust tips onto the tail pipe.
Step 10: Straighten all exhaust components and begin to tighten down all clamps beginning at the front and ending at the rear.
Step 11: Double check all work and ensure everything is tight. Congratulations, your system is now complete and full.
Step 12: It is recommended to re-tighten all clamps and bolts after 50-100 miles.
