Headers for 4.0 liter MJ...Banks or Pace Setter

[jiffyjet2]

My '89 MJ, 4.0 with 5 speed short bed, is in need of some exhaust system renovation. I'd really like to put a set of Banks headers on it, but they list their Comanche header for '91 to '92 only. I talked to Banks to find out what the difference is between early 4.0 and later, but they couldn't answer the question. Is there a huge difference between the exhaust on the later engine and the older engine? Could the Banks headers be tweaked to work on my Jeep? The other brand says some modification MAY be necessary too. Any help or advice is gladly appreciated.

I have a SS Banks header on my TJ. I've had it for a couple years now with zero issues, its a nice unit.

You'd be hard pressed to put a SET of headers on a straight 6. There's only ONE exhaust manifold.

Thanks for the insightful comment, nothing like some idiot trying for a laugh when you're trying to get some information.

I run the Pacesetter header on my 87. It's a nice unit and it came with everything need. No issues with the install either. I'd buy it again.

Take it easy now.

if you want to get technical, each individual pipe is actually a header, so the manifold on a I6 is actually a set of headers....

Your actually one of the only one's I've ever heard say that. I take it you don't have an AW4 tranny? Their are some major clearance issues with the AW4 and that header.

 

However for the $$ I will say it's a nice header and do like the fact that it includes a down pipe as well.

so that one can be made into a true dual exhaust?

If one panty can be a pair, why can't one header be a set?

:huh???:

Anyway ordering a set of pacesetters, thanks to the testimonials given here.I'm ordering two sets. I need two AND to add more confusion to the issue. HEHE

You sure about that?

 

This is a 2 piece inline six header.

Looks like a three piece header
