Warning: 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·lfworking 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
-NOTICE- Fascia needs to be modified (cut) to install this Magnaflow exhaust system.
Step 1:(Carefully read all instructions before installation) To remove the OEM mufflers, first locate the ball flare clamp assembly attached to the inlet section of both mufflers. Remove the clamp from both the passenger and driver side, then remove the hangers from the rubber isolators (three on each side). Do not damage the OEM rubber isolators as they will be reused to mount your new Magnafiow system. Remove the mufflers.
Step 2: At this pOint you will need to cut the fascia to allow installation of the new exhaust system. Using the supplied template in the hardware kit enlarge the exhaust openings in the fascia fOllowing the instructions printed on the template. (see Fig.1)
Step 3: Once the fascia has been modified use the OEM clamps from the muffler assemblies to secure Magnaflow Competition Series Mufflers to the exhaust system. Locate all hangers to the rubber exhaust system isolators.
Step 4: With all components fitted loosely, adjust the system for overall aesthetics and clearance of the 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.)
Step 5: Once a final position has been chosen for the new system, evenly tighten all fasteners from front to rear. The OEM clamps must be very tight to properly align the pipes and prevent leaks (approx 40ft/lbs). Inspect all fasteners after 25-50 miles of operation and retighten if necessary.
