    This Rugged Ridge Replacement Exhaust Manifold is for those of you that have a 2007 to 2011 JK with the 3.8-liter engine and are looking for replacement exhaust manifold because yours is cracked or otherwise rusted out. If you're somebody who does a lot of deep water crossings, plays in a lot of mud, when you have a very hot exhaust manifold making contact those very cold liquids, you can often times get a crack. And it's not often easy to fix an exhaust manifold by welding it. You'll end up with a very strong section when it's welded and you'll just end up with a new crack right next to your weld. So, replacement is often the best option. These are, of course, available from both the driver and the passenger side of your 3.8-liter and you can also get this as a pair if you need both of them. These are also available in stainless steel. So if you're looking to keep the rust at bay, you don't wanna go with a mild steel manifold like it was on your jeep from the factory. You can upgrade to the stainless but, of course, it is going to be more expensive.This manifold is going to be cast iron. It is going to be a direct replacement for your factory exhaust manifold, so you're not going to get any sort of benefits out of this like you would a header. Oftentimes, a header has a slightly larger port, it has a different design to allow greater flow, it might be something similar to a long tube header which is designed to give you some additional torque and/or horsepower. This is just going to be a straight replacement. It's not going to be any additional power or any additional benefits. However, this is going to save you some money over going to Mopar for a factory OEM replacement.The install for this header is going to be a little bit of an involved process and I am going to give it a two out of three wrenches. You're going to need pretty much every tool in your toolbox in order to get this installed. The process really starts by doing the disassembly, removing your collector off the end your exhaust manifold. You're going to have to remove all of the bolts that are holding the manifold in place and then replace it with the new manifold and a new gasket while you're at it. Now, you can run into a lot of issues when you're working with exhaust because you will have some rust on it. And often times, its bolts and the studs get brittle and also rusted, so you can end up with some broken bolts. It's definitely a good idea to spray everything with a good penetrating oil well before you get started with this install to help avoid any of that breakage.Now, getting the old exhaust manifold off and getting the new one on is really just a matter of a couple of bolts but the difficult part, the time-consuming part comes from removing everything else that you might need to remove to get to this location because it is going to be a little bit tight in there. You're gonna have to work from both the top and the bottom side of the engine. If this is not something you're comfortable with, I would definitely recommend taking your jeep to a shop and having them install this. It will probably save you some headaches.This manifold will run you right around $150 for one and about double that for the pair which you would expect. And again, this is gonna be less expensive than if you are to go Mopar and get a replacement exhaust manifold. These are also going to be less expensive than the stainless version from Rugged Ridge. But either way, they are going to get the job done. They're going to be as similar as you can possibly get to and OEM exhaust manifold. And if you're looking for a replacement, I think this is going to be a really good way to go to save you a few dollars.So, if you need to replace your exhaust manifold, I would definitely recommend taking a look at this one from Rugged Ridge that you can find right here at ExtremeTerrain.com.

      3.8 Headers

      Great replacement for stock manifolds. I coated mine with VHT flame proof ceramic primer and paint after I cleaned em up with oven cleaner. Improved fuel mileage and downshifting on the highway.
