Performance headers on '98 TJ I6 ????

I have a cracked exhaust manifold. It is cracked at the collectors just ahead of the flange.
The shop wants 4 hours labor and $400 for the replacement part with the expansion bellows.

I can find similar parts for $175 +/- 25 thru various online parts suppliers.

If I am going to do this myself, I was thinking about performance headers instead of the improved (bellows) stock system....

Any recommendations? Yes/No? Brands ? Any issues to watch for ( like CEL, need for a tune, other codes?) Is there a DIY with pics somewhere on the Jeep install?

All advice welcome.
Thanks in advance.

Do it yourself and use the factory replacement

License to kill gophers by the government of the United Nations. Man, free to kill gophers at will. To kill, you must know your enemy, and in this case my enemy is a varmint. And a varmint will never quit - ever. They're like the Viet Cong - Varmint Cong. So you have to fall back on superior intelligence and superior firepower. And that's all she wrote.

get the 2-piece cast manifolds of a 2000+ TJ, XJ or WJ. Then buy the Walker Y-shaped downpipe for a 2000 TJ.

Problem solved, and you'll never have to worry about it again.

^Would this combo make it harder for the single O2 sensor to do its job on the older model 4.0Ls. Ive been considering this for a while and just wonder if the computer is tuned to have the O2 a certain distance away from the exhaust ports. From my understanding the O2 plays a role in determining what cylinder is misfiring .
