How to Install Magnaflow MF Series Cat-Back Exhaust - Single Side Exit on your F-150

Step 1. To remove the OEM exhaust system, loosen the clamp attaching the systems inlet pipes to the catalytic converter outlet pipes. Disengage all welded hangers from the OEM rubber insulators. Do not discard the OEM fasteners or damage the rubber insulators as they will be needed to mount your new MAGNAFLOW system. 

Step 2. Install the new system by attaching the Inlet Pipe Assembly to the OEM catalytic converter outlet pipes using the existing clamp and hardware. Locate the welded hanger to the rubber insulator. Leave all clamps and fasteners loose for final adjustment of the complete system once installed.

Step 3. Install the Muffler Assembly to the Inlet Pipe Assembly using the supplied 3.00" clamp. 

Step 4. Install the Over Axle Pipe using the supplied 3.00" clamps. Locate the welded hanger to the OEM rubber insulator.

Step 5. Finish installing the components by sliding the Tailpipe Assembly onto the Over Axle Pipe and fastening with a supplied 3.00" Clamp. Fit the hanger into the rubber insulator.

Step 6. Once a final position has been chosen for the new exhaust system, evenly tighten all clamps from front to rear using the torque specifications on page one of the instructions. Inspect all fasteners after 25-50 miles of operation and re-tighten if necessary.
