I got one from pacesetter a few years back, not sure if they still make one, the only thing I didn't like about it is the 02 sensor port moved down right before the cat, and the egr tube didn't really line up will. But it works well and better then the stock manifold, i think it was 230 or so I paid

I thought the cat was by the t-case on a renix, it is (was) on my 1990 anyways...my o2 sensor is right on the manifold...

Yeah on my factory manifold had the 02 sensor on it, the pacesetter kit comes with the header, the down pipe and the pipe that goes just before the cat with the flange, for some reason they have the 02 sensor port down on pipe with the flange that bolts up to the cat. The pacesetter kit downs come with wires to extend the 02 sensor harness

I need one of these.

But I don't like the o2 relocation idea.

X2. I would almost consider welding a bung back where it should be. But not before I tried it the way it comes...

I don't think that's possible.

The way the header looked there are two runners that go quite a ways lower than their original placement. Im guessing they did that to deal with the yoke of the front DS. Either way, they effectively forced us to put the o2 lower as ours are used to seeing all 6 exhaust ports, and any higher it'd only see 3.

what year is ur jeep? they make headers for it but alot of them say 91 and up. i had a 1990 and wanted a header and i had fuel injection. 90 was split years for fuel injection and carborated. if u have a 1990 with fuel injection a 91 and up header will fit. i found one on a website a while back with a header for $250 it said was proven equality to the banks header.
