Headers or stock manifold?

[JeepGuy24]

Thanks for the advice. Mine is a daily driver Wagoneer, some towing (19' power boat), some sand (Hatteras). I need a new Y-pipe, so I'm trying to figure out what I should plan on replacing while I'm at it. Exhaust is about 4 yrs old (Middas/stock). I'm going to be flowing more air into the engine....time to get it out.

I have had to take every set of headers that I have ever gotten and weld around flange to tube joint and then gasket match them with a die grinder, I sure hope for the $ that the Edelbrock or Thorley headers fit without this.

As for the Headman headers they do hit the pan w/a auto on the passenger side (Tf-999 that is).


Statement/Question:
I have a set of stock exhaust manifolds off of a 78' J-10 I was told that they will not work on a CJ since they do not bend down quick enough & that thet will hit the fire wall, is there any truth to this. I haven't installed the tub yet so I don't know if they will hit.

Thanks,

I have heard the same thing before, but I have no first hand experience. I think one of them fits and the other doesn't. I think it was the passenger side manifold that doesn't fit?

Hummmm, thanks.

Can anyone confirm this?

Can/if it is the passenger side can a 90* bend be added just after the manifold to make it work OR will it just not work?

Thanks,

Well I took the passenger side Stock manifold off of my J-10 (1984)Left over after header install and replaced a cracked stocker on a 1977 CJ-5. As near as I could tell they were identical in all respects, everything bolted right back up..

So my guess is if they work on a 5 they will also work on a 7..

So my guess is if they work on a 5 they will also work on a 7..

I would give a definate maybe All things considered, the changes between a 5 and 7 were under the seats and location of the skid, so what's forward of that is interchangeable fenders, rad, round lights So as ling as you haven't changed anything with the engine mount locations should be good-to-go

I used hedman in frame with my T-400 auto in my 83 CJ-7. they clear everything. Not even close to having contact with anything the entire length of the tube. But the flanges have to be the worst fitting pieces of junk I have ever seen. I installed Race-pro copper gaskets tourqed everything down, fired the ole' girl up and it sounded like 22rimfire bullets going off under the hood. Removed the hedders and found that the crush zones on the copper gaskets were in a lot of cases overlapping the exhaust port. No way to seal if there is nothing available to crush a gasket between. Did the whole cut the tie bar, grind, hammer, grind, hammer. but if the flange mounting holes don't allow the ports to line up there is only so much you can do. I run Hooker now and am O.K. with them. Seems to be a twin to the Hedman but the flanges line up much better.

Ohh I agree.. I would never buy the cheapies again.. This is definately one area where a few extra bucks prevents years aof aggravation...
