I just swapped a 2000 4.0 into a 1997 .problem is I cut the headers on the 2000 motor when taking it out. Can I use the 1997 ones? I know the exhaust ports are smaller but will it still work?

Gee oh Dee

Ouch.

I think you can, do the holes line up?

I know the 2000 and 2001 have the cast intake manifold, 4 o2 sensors and 2 cats IIRC. I have a 99 xj which has the 00-01 intake manifold but older style header.

Anyway if the 99,00,01 have the same head, then couldnt you use a header that fits a 99. Unless, are the heads completely different from 99 and older to 00-01?

Just go with a Banks..........

Gee oh Dee

Yeah. For something like $500.

Hey, I never said it was cheap. I did with my old TJ and was happy. I guess I go by the philosophy of "If your gonna do it right, do it right the first time." That thing is a PITA to replace. I'd rather only do it once........

What's the best way to get the bolts out? I heard that if you just cut all the heads out you can then get vice grips on them and get them out?

Gee oh Dee

I have a Borla header for my wifes TJ. But I only paid $100 for it slightly used.

Have you tried to get them off yet?

Ive pulled the manifolds a few times no problem its the flange at the bottom that breaks studs heat soak in pb blaster impact on low speed go to go

Im sending the head from the 97 out to get checked for cracks. Just going to use that one. It's the better head anyway
