WJ performance headers?

everyone knows that headers give you the best performance you can get outta your motor with out doing anything crazy to the internals. does anyone know a company that sells headers for the WJ with the o2 sensor points built in? ive been looking but i havent been satified with my results. any suggestions?

thanks

Re: WJ performance headers?

I think Gibson does Headers! You should look into getting your 4.0L Stroked to a 4.6L!

I don't think there are any choices for the 4.0 either.

Re: WJ performance headers?

ive got the 1999 jeep wj with the 4.0. I was wondering of any bolt on mods that would give mea little more power. I already have a throttle body spacer, the four hole injectors, cold air intake, high flow cat and a cat back. I am ordering the banks header soon along with the bbk throttle body itself. I noticed a big difference with just those mods any suggestions.
