Best performing headers?

My exhaust manifold is cracked in like 3 places so I want to switch to headers hoping they will stand up to the heat of the 4.0's I6 better. I was wondering if anyone had an opinion on which brand was any better than the other. I'm a college student so I'm somewhat budget minded, but I'm not going to waste money on Rugged Ridge or anything and have it crack in less than a year. I've also read that the 2-piece manifolds hold up a bit better, does anyone have any experience with these? how was the install?

all 2000+ TJ's came with 2-piece exhaust manifolds...so theres lots of folks driving around without a crack.

look into doing the 2-piece manifold swap with a walker intermediate pipe.

ive had the raw steel rugged ridge for almost 4 years now w/o a crack on it. But i agree if you could find a 2 peice header and create some time of adaptation to fit our head pipe it would be much much less likely to crack.

Thanks for the info. I'm thinking Borla it is. They do offer a one million mile warranty; can't really beat that. They also have a 2 piece, I assume for the 2000+ models, might try to adapt that to my setup.

how is a million mile warranty good if you have to take the manifold off every few months when it cracks, assuming they honor their warranty?

They honor their warranty without question. A few years ago I bought a Cracked Borla header from a friend of mine for 50.00, I figured I would weld the crack and have a good header for my TJ. I read about the million mile warranty and called Borla. Without question, they sent me a return authorization I sent in the cracked header and they sent me a brand new one! It has been on my 98 TJ for 8 years so far with no problems whatsoever.

Borla's (Banks too) one-piece headers are well known for cracking and their "million mile warranty" doesn't also magically get the free replacements installed.

The only way I'd install a Borla is by going with their two piece design which can make the installation and 02 sensor placement problematic.

Personally I'd stick with a one-piece replacement header that has the improved crack-resistant design that adds replacement flexible steel accordan joints where the cracks form which cures the cracking problem.

The newer crack resistant design Jeep later went to looks like the below header (the flex joints are circled in red) which is available all over eBay for a pretty inexpensive price.

Definitely going to look into that. The flex joints do seem like they would be ideal for taking some of the load and vibration from the engine movement which seems to be one of the causes of the cracks appearing in the first place. And it's a way better value, $130 vs. Borla for $400, yeah definitely gonna try that one out.

What I can't understand is why neither Borla nor Banks have installed the flex joints that would stop theirs from cracking. Even the cheap import headers have them. Jeep upgraded their headers to include the flex joints back in '99 or so to fix their problem with cracked headers. I had three cracked headers replaced on my '97 before Jeep came out with the improved header which fixed the problem.

That is odd that they don't. Do the flex joints possibly change the tone of the exhaust? I've read a lot about people choosing them simply for the sound.

Headers are not going to affect the sound.

While I'd agree a flex joint may correct the cracking issue, a corrugated section is counter productive to the theory of a header which is less restriction and smooth flow.

True.

If the header user was looking to break the record at the Winternational drag races, I would say that may be something to consider. Since I doubt any of us running the 4.0L are doing anything like that, I'd have to say the flex header is all benefit with no drawbacks.

Jerry I'm fixing to order my third header for my Jeep, the one i just installed 8 months ago has the flex joints and still cracked on me. I did buy it on ebay for a 100 bucks so maybe the material wasn't as good or what. Where do you suggest I buy one?
