89JEEPYJ they all do the same job for the most part. I have borla and they sound ok but they hit everything and are a pain. Summit racing headers are pritty nice

What Headers do I need for a 4.2L with Mopar MPI

Hey guys,

I've got a '90 YJ and have installed the Mopar MPI on it (Love it BTW). I'm looking to install some aftermarket headers on it. Does anyone know if I should order headers for a 4.2L motor, or 4.0 motor? How about brand? I don't have a ton of cash to spend, but i plan on having this Jeep forever, so I don't want to go too cheap either.

Thanks a ton!
