Do I have a header?

I know this sounds like a stupid question, but I just ordered a header, and I'm really hoping I don't already have one. I bought my Jeep with everything on it already, and nothing was ever mentioned about a header. I don't know what stock equipment looks like on these things. This a stock 4.0 manifold?

X2 looks like a header to me from the top cause of the round tube.

However... if you look under your rig into the engine compartment there will be about 4 "tubes" coming down into one going into the exhaust pipe, thats a header... if not then you have a manifold, but pretty sure that's a header system.

An eBay header, not sure of the brand. Thought it would be better than stock, not realizing I don't have stock. I kinda screwed up on this one...Really shoulda checked if I wasn't SURE about what I have. Ya live and ya learn. We'll just see when it gets here the size of everything and how it compares. Maybe its a lot better quality.

Damn that makes me feel a lot better. Thats sad how sure some people were its a header. Well the actual one arrived in the mail today right as I was getting home from work, so its goin on this weekend. I need the fuel line clip disconnector things, right? Any other particular tools most people might not have? Thanks guys

That's definately a factory tube exhaust manifold...and prone to cracking in the lower flange area.

I got a great deal on a header on E-bay. The install wasn't all that difficult and I noticed a BIG difference in available torque (that's with the "butt dyno"...I have yet to run it on a REAL dyno...probably never will).

My header install came out of need...my factory junk cracked right where it did on my buddy's rig. Up next? A Dynomax cat-back system. I hope to get some nice rumble out of my old 6 popper.
