How to Install a Magnaflow Rockcrawler Exhaust On Your 2007-2011 Jeep Wrangler JK 2 Door

When working on, under, or around any vehicle exercise caution. Please allow the vehicle's exhaust system to cool before removal, as exhaust system temperatures may cause severe burns. If working without a lift, always consult vehicle manual for correct lifting specifications. Always wear safety glasses and ensure a safe work area. Serious injury or death could occur if safety measures are not followed.

** Magnaflow Performance Exhaust recommends professional installation on all their products

(Carefully read all instructions before installation) Unbolt the clamps at the inlet and over-axle pipe, to remove the OEM exhaust system. Disengage the welded hangers from the rubber insulators and remove the components. You may need to temporarily remove the transmission skid plate to aid in removal and installation. Retain rubber insulators as they will be used in the installation of your new system.

Begin installation of the new system by fitting the Inlet Pipe Assembly to the catalytic converter, fitting the hanger into the rubber insulator, and by fastening it with the supplied 2.50 inch clamp. Be sure to fit the alignment peg in the large notch and to leave the clamp loose for final adjustment of the complete system. install the Muffler, Extension and Tail Pipe Assembly is a similar fashion leaving all clamps loose for final adjustment

With all components mounted loosely, adjust the system for overall aesthetics and clearance of frame & bodywork. (MAGNAFLOW recommends at least 1/2" of clearance between the exhaust system and any body panels to prevent heat-related body damage or fire.)

Once a final position has been chosen for the new system, evenly tighten all fasteners from front to rear. The supplied band clamps must be VERY tight to properly align the pipes and prevent leaks (Approximately 40ft-lbs). Inspect all fasteners after 25-50 miles of operation and retighten if necessary.
