2wd headers on a 4x4?

[Russell]

Any chance my headers for a 2wd will fit my 3/4 ton 4wheeler? She'll be running a 2 wheel drive transmission with a divorced transfercase

I dont see why they wouldnt.....Im running headers fit for a Chevelle.....just takes a lil bit of heat and a BFH or gentle persuader....along with some time an lots of beer.

Truthfully, I think that they will work. I had a set of headers on my 4x2 that I moved to my 4x4 for a little while, and I didnt have any issues.

Sounds good, cause I've got an awesome exhaust setup on my current 2wd truck, and I really don't want to have to buy a new set of headers and a new exhaust setup, lol

i've got a set that came off of my 86 when it was a C10, im gonna try to make them fit. even if there were clearance issues, mine wouldnt be as bad as some, since my front shackles are moved forward several inches.

I run 2wd doug thorley's on my 4x4.. But I had to heat and bend the passenger side set to clear spring shackles... from what Ive gathered, MOST brands of 2wd headers wont fit a 4x4....

you'll have to buy a new setup. there's a little thing in the way of pipe routing called the transfer case.

I won't be running a stock t-case, may be able to get around it yet

If not, I guess I'll drop the money for a new kit..

if you're running anything offered by GM, you'll have problems. the only way i could see getting around it would be something physically smaller, like an Atlas or something, and even then it probably wouldnt help a whole lot. plus, an Atlas is $$$

Mine fits real snug, Ive got an SM465/NP205, my headers are the long tube Hooker Supercomp, with 2 1/8 primaries into a 3 1/2 collector. From there it is reduced to a 3" pipe into dual 3" flows, with dumps just infront of the rear axle. My passenger side header is about 1/2" from the starter, 3/8" from the passenger firewall on the topside, and the exhaust pipe is bent around the t case, so that even with motor torque, there is no rubbing between the two. Like I said though, it just takes a little creativity with a torch, prybar, BFH and some beer. BTW, this is all on a BBC, so if you are running a SBC, you have even more room to work with.

Just my .02$

[Russell]

Probally just don't know the first thing about the 4x4s, but yeah, my exhaust hugs the frame rails the whole way back, so maybe the t-case won't be in the way?

We'll see...

When I bought my new headers the box had 2x4 and 4x4 both listed as applications.

It`s the t-case crossmember you need to get around.Takes a 45deg/45deg to get over it.

[Russell]

If it is a matter of just installing a couple 45 degree pipes in, no big deal then... The pipes are totally straight the whole way back, so a guy could easily cut and install the new pipes
