If you've been following our YouTube channel, you've seen me install quite a few exhausts on our 2008 Jeep Wrangler, but we want to show you as many options as we can so you can choose the best one for you. Today we're going to give our Jeep some better ground clearance and a better sound by installing this MagnaFlow Rock Crawler Cat-Back exhaust. This MagnaFlow Cat-Back exhaust is made of two and a half inch mandrel-bent stainless steel tubing, with a turndown tail pipe, and moves the muffler towards the front for better ground clearance and sound. It comes with everything you need for an easy installation, so today we're going to install it on our 2008 Jeep Wrangler. Tools you'll need for this installation, 15 millimeter socket, half inch ratchet, 15 millimeter wrench, and you'll probably need an exhaust hanger remover tool.

All right, so installing Cat-Back exhaust on the JK Wrangler is actually pretty simple. We're just going to get the Jeep up in the air, remove the factory axle back, then work our way towards the front. This nut is so corroded it's actually supposed to be a 15 millimeter, but this 12 is just barely too small, so we're going to hammer this 12 on and hopefully it can grip on to the nut and we can break it free. All right, hopefully you don't have to do this, you probably won't have to, but we're going to take a cut off wheel, we're going to cut right there and that should break it free.

Now we're going to remove the passenger side rubber hanger, you might need an exhaust hanger remover tool for this. These factory hangers can be pretty stiff. We're going to pop the driver’s side hanger off, and then we should be able to wiggle the muffler off and pull it right off the over axle pipe, same process as the passenger side.

All right, we've got the factory muffler off, now we're up front at this front pipe and we need to disconnect a clamp. However, it suffered the same fate that our muffler did, and the nut is pretty much non-existent. We're going to have to cut the clamp again, right on the pipe, just like we did on the muffler.

Now we're going to remove the rubber hanger on the front of the front pipe and finally remove the hanger near the axle. Before you can drop the exhaust you actually have to drop down this skid plate here. You don't have to completely remove it, you can just undo this bolt and this bolt and then loosen the front two and let it hang down. If you don't remove it, the exhaust just kind of hangs here and you can't get it out, so you definitely have to get this out of the way.

Okay, with the skid plate down, now we're going to twist the exhaust to pull it off, and she's out. This is why you had to drop the skid plate, the exhaust needs to slide out right there. Now, you can completely remove the pipe.

All right, with the factory system out of the way, we're now going to install the MagnaFlow front pipe with a clamp onto the "Y" pipe. Slide it all the way on, then get it into the rubber hanger. Place a clamp over the front pipe, then install your MagnaFlow muffler, and your extension pipe along with a clamp. Next is going to be your over axle pipe. Get the over axle pipe into the rubber hanger as well. Finally, install your tail pipe.

Now you just need to go back and tighten all the clamps, and reinstall the skid plate. Tighten all the clamps with a 15 millimeter socket. Finally, reinstall the skid plate, and your installation is finished.

All right, let's hear it. All right, we've got our MagnaFlow Cat-Back exhaust installed, it looks way better than the factory exhaust. I'm so glad we got that rusty thing out of there. It's hooked up nice and high, gives us a bit more ground clearance, and sounds a lot better too, but we still have an exhaust leak up front, but we will fix that later. Installation's not too bad, should only take you about 30 to 45 minutes, and before you know it, you'll be heading off road.
