How to Install the MagnaFlow Stainless Steel Cat-Back Exhaust System on a 2006 Ford F-150


Today on our 2006 Ford F-150 we'll be installing the MagnaFlow Stainless Steel Cat-Back Exhaust System part number MF16616. To begin our install, we'll first need to remove the old or manufacturer's exhaust. Starting at the clamp just behind the Y pipe of the exhaust, we're going to spray it down with some spray lubricant. Note over time this clamp will rust up and can be extremely difficult to get off. In severe cases it may even break. If that happens, it'll be necessary to replace it. In an event where it's so rusted that you can't get a wrench or socket to hold, we'll use a pair of vise grips to try and break it free.

Another method is to heat them up with a torch. Now that we've got our front clamp loose, we're going to go ahead and spray each one of the hangers with a spray lubricant to make it easier to remove the old exhaust. Now because of the excessive corrosion and weakness of the old clamp from having to heat it up with the torch to remove it, we've gone ahead and purchased a new one from the dealer. We'll go ahead and slide it onto the Y pipe first. Next we'll go ahead and take the new exhaust pipe and slide it into the clamp. Next we'll install the provided clamp onto the exhaust pipe.

This will secure the muffler to the exhaust pipe. Now for this application, we're going to need to trim down our inlet or exhaust pipe going off the edge where it faces the Y pipe or the front clamp. We'll measure back six inches. Mark it and then to cut it you could use a chop saw, sawzall or even a chain cutter. We're going to use a chain cutter because it allows us to get a little bit cleaner of a cut than using a sawzall. Now that we've got the six inch piece cut off, we're ready to install our new inlet pipe. We'll go ahead and install it into the front clamp and then slide the muffler clamp onto the pipe.

Next we'll need to install the new tailpipe hanger. The hanger will fit into the pre-drilled hole here at the front of the shackle. To secure it, we'll install the flange nut onto the hanger first. Now with the nut in place, we'll install a flat washer, put it into the hole. We'll install a second flat washer and a second flange nut.

Once in place, we can go ahead and tighten it down. Now with our hanger and isolator in place, we're ready to install the muffler and tailpipe. I'll go ahead and spray the rubber isolators first for ease in installation of the new hangers. You'll note that we've left the protective packing on the tailpipe and muffler to help protect it as we install it. Quick tech tip: if you're having difficulties lining up the hangers and the exhaust pipe at the same time, you can actually take the exhaust pipe down because of the slide through clamp, we can reinstall it after the muffler's been positioned. We'll slide the exhaust pipe onto the neck of the muffler, line our pipe back up and slide the clamps back into place. With our clamps in position, we can start tightening down the new exhaust system. When tightening down the exhaust system, we'll start at the front and work our way back. Now before we tighten down the muffler clamp, we'll make any adjustments necessary to the muffler and tailpipe. Special note, you want to make sure that the tailpipes are facing at a slight down angle and not facing up so that they collect moisture or condensation in the tailpipe and muffler. Now that we've got our exhaust tightened down and secured, we'll go ahead and remove the protective cover. Before the engine gets really hot, feel around each of the seams or clamps to make sure you've got a good tight seal. Now that we've verified we don't have any leaks, that'll complete our install of the MagnaFlow Cat-Back Exhaust System part number MF16616 on our 2006 Ford F-150. .
