good 4.0 exhaust manifold / header

Recommended Posts

Hi,

 

I am looking to replace the cracked exhaust manifold on my 1991 4.0 YJ. Can anyone make any recommendations on manifolds and headers? I don't want to go cheap and have the new one crack soon after. Any tips for removing the old bolts? Penetrating oil and heat?

 

Thanks in advance.

I used a Napa one, About $100 with lifetime guarantee. Are your bolts rusty? Mine came right out, always an AZ jeep.

We're on our 3rd one on Clifford. We got the first two off craigslist; they each lasted a couple years. Now we have a Banks ($$$). It's been on about a year, so far so good.

I would do the factory style manifold like Tim did with life time warranty. I paid $400 for the Banks thinking it would add power. I did not notice any power gains and it was harder to install because it was harder to get to the bolts and only a 5 year warranty. :)
