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

Installation Time

2 hours

Tools Required
  • 15mm & 10mm Sockets
  • Ratchet
  • Jack
  • WD-40

Remove Stock Exhaust

Step 1: Start by unbolting the center exhaust clamp.


Step 2: Next remove the stock exhaust from the hangers found in these three locations.


Tip: Unbolt all hangers using a 10 mm socket instead of trying to pry the stock exhaust out of the hangers when removing the stock exhaust. You can easily reinstall the hangers while test fitting your new catback.

Step 3: The stock exhaust must be rotated counter clockwise to unlock the factory grooves before you can fully disconnect the stock exhaust.



Step 4: At this point the stock exhaust should be fully disconnected, dropped and resting on the rear axle. Simply pull the stock exhaust over the rear axle towards the front of the truck to complete the removal.

Tip: For those garage warriors without a lift: To get the stock exhaust completely off of the truck, simply jack the passenger side up about 3 inches so that the over the axel (bent pipe that connects to the exhaust tip) pipe has plenty of clearance to slide out.


Magnaflow Cat-Back Install

Work your way from front to back and keep everything loose until the proper position is obtained.

Step 1: Start by installing the first pipe and reinstalling the rubber factory hanger.


Step 2: Next, install the Magnaflow muffler as well as the factory muffler hanger. Use the supplied band clamp to couple together the new piping.


Step 3: Now install the new over the axle pipe by using the supplied band clamp on the muffler.


Step 4: Lastly, reinstall the remaining factory muffler hanger and connect the final pipe. This piece will require you to connect back over the axle pipe, couple the connection, and ensure the exhaust tip is in the desired position.
