XJ 4.0 headers

Who has them, what brand, durability/longevity, is it worth the money vs. horsepower gain (seat of the pants meter). Thanks.

For just over $100, I gave the eBay Chinese header a try. It held up 2 years ECORS racing, seemed to flow better than the stock manifold, definitely quicker throttle response.

I guess I should have also asked what other mods were done. I have a cai and bored TB on mine (97 XJ 4.0/AW4). And..... Go...

Four home injectors like off a neon give a better throttle response but flow same amount as stock

I had a banks, I got it when I built the stoker, loved the exhaust, never cracked when I had it for the years i did DD the jeep before I sold it. Pricey though, I had the 99-00 for the XJ with the cats up top in the Y.
