91 YJ header on a non HO XJ 4.0?

Maybe some of you wrangler guys can help me out here, Will an exhaust header from a 91 YJ 4.0 bolt up to a Renix 4.0 head on an 87 XJ? I know I'll have to get a downpipe made but that's no big deal. Its a borla header if that makes any difference. Thanks

91 YJ 4.0L is an HO.

Your Renix pipe has a port for EGR & the O2 sensor.

Swapping in an HO pipe would eliminate the EGR, and you'd have to put the O2 sensor in the downpipe (like the HO's did).

Other than that, I believe it does bolt up.

Thanks, I wasn't sure what 4.0s the YJs used, I could care less about the EGR stuff, no emissions inspections here, and I've already disabled most of it anyway.
