Here are the items you'll need for this repair: 14mm socket, ratchet, socket extension, flat head screwdriver, penetrating oil, jack and jack stands

Raise and support your vehicle. We're using a lift to make it easier to show you, but this job can easily be done in the driveway on a jack and jack stands. Now, normally we would show you how to replace each individual portion of the exhaust, but our entire exhaust system right from the manifold back is rotted beyond the point of repair, so we'll have to replace the entire thing.

The first big issue we noticed is the flex pipe; it has rotted away. All this mesh is coming off and it's actually split in the middle. You can hear the exhaust leaking out of here when the vehicle's running. Now, normally we could change this front cat pipe, however there is nothing left on these flanges. The hardware that's in there isn't even recognizable anymore, so even if we did get these out and get new hardware in, the flanges are too corroded for us to be confident in them sealing correctly.

Our midpipe has the same issue, rotted all the way back here at the muffler, so we can't expect this to come off and reseal properly either. The muffler itself is completely rotting through. In the case on the side, see how soft the metal is there? So we have to replace our entire exhaust system.

To remove just the muffler, undo these two nuts on the flange. Separate it and remove the front and rear hangers.

To remove the exhaust hangers, spray them with some penetrating oil. There’s one at the front of the muffler and one at the rear. Slide them off the studs by hand, and remove your muffler.

Remove the hangers from the stud. It may help to use a flat blade screwdriver since these ones are pretty tight to the muffler. Do the same thing with the rear most hanger.

Our muffler is almost identical with the same bend and support, as well as the two bolt flange with the studs already welded in, the same hanger in the back, and our front hanger actually faces in the opposite direction as factory but it will make our installing our muffler a little bit easier.

Reinstall the muffler into its hangers. It should just press right on. Make sure you clean the surfaces if you're using an old pipe. We have a new one, so we'll just install a new gasket onto our flange.

Mount the muffler and the midpipe together. We have two 14 millimeter flange nuts that we had in the shop. If you saved your old hardware, these studs are OEM size so, you can just reuse it, but ours was corroded, so we'll have to replace it with this stuff that we had. Tighten it down with a 14 millimeter socket and ratchet. Especially when using old exhaust parts, if you are able to, you want to get these down as tight as you possibly can without breaking them. This stuff can be a little tricky to get to seal properly.
