best headers/exhaust system for 4.0 ohv

[stamina]

i recently acquired a BBK 66mm throttle body from a junkyard 4.0 and after installing it has genuinely made a change in the way the truck responds when you hit the gas, it’s just plain faster/stronger in every way. on this power trip i am looking for a set of headers for the truck, what have y’all bought/tried and what has worked/not been good or not fit right. current setup is stocks manifolds, stock y pipe, stock cats, and then coming out the intermediate pipe. i am planning on keeping the cats + getting a side exit off the intermediate pipe. am open to any ideas for the entire exhaust system.

AFAIK, JBA makes the only 4.0 OHV headers. I put a Gibson cat-back on my old Sport Trac, fit like a glove, kinda loud but sounded good for a V6. No headers.

I just picked up a BBK 66mm and was thinking of adding headers. I haven’t gotten mine on yet. I’m glad to hear you liked them. Let us know if you get headers and what you think.
