yet to be determined
New headers are done!!! I was having problems blowing collector and manifold gaskets, and it was determined that I had too much back pressure with my shorty headers. I took the Bronco to a guy in Auburn, WA and had him build me a custom set of 1 3/4" long tubes and he added 3" mandrel bent dual exhaust. He said it sounds wicked!!! It is going back on the dyno tomorrow for tuning. Can't wait to see and hear the results!!!!

Pictures are before and after, Old headers vs new headers, and how we ran the exhaust.

Gotta be Stans. nobody in the Valley but Stans can do that kind of quality,
Directly between where you got your headers and where you took yours to the Dyno is the Best machine shop onn the West coast. But damn his work is spendy

ok, so how much will a set cost me?


Since I have alot of time in R&D not to cost effective right now. I have been talking with the owner, Dan, and he asked how many others might be interested in this type of setup. Since most of the R&D is done, it should be cost effective.

So who might be interested in a set???

Let me know and I will let him know. One real advantage to this setup is that it is out of the way. You can still do your 4 links, traction bars, shocks, whatever. You can also remove trans and t case without touching the exhaust. I can even see you getting a complete system with mufflers.

We're definitely gonna need some audio clips of it running. This thread needs more Bronco porn;D Looks like it's all out side the framerail though, so you're not running your aux. tank?

Tempting. I'd be interested in the price as well. Think he would offer the headers and a "starter pipe" with the flange on it for the exhaust back side?

Looks like they will breath a lot better. I had mine ceramic coated. I'm told they should stay looking good.

Ok, headers are done, and jigs have been made for any of you guys interested in a set of these headers. If we can get enough order through a mass buy we can see some savings.

Fitment on A 302 is unknown as of now. We need to do a test fit on another 351w equipped bronco to make sure everything fits good. The real advantage of these headers is that they exit outside the frame rail. There is no need to remove exhaust when working on drivetrain. Also makes a more room for a 4 link in the rear.

Here are the current requirements for installtion of the headers.


351W V8 with extreme motor mounts
Modification to drivers side inner fender. Need to remove a little material.
Relocation of the brake proportioning valve. Needs to be moved forward a inch or two.
Removal of auxilary gas tank
See pictures in first post

Pricing is below. 2 1/2" is available also same price. Kit should be bolt on other than modifications listed above.

Let me know what everyone thinks. Guys with the larger cubic inch engines would really benefit from these.

Here are the retail prices with available discounts:

$375.00 for a 2 1/2" or 3" aluminized exhaust: 14 gage tubing with Spintech Sportsman Street XL or Flowmaster mufflers and turn-down tips out the side under the doors.

$495.00 for the 4 into 1 headers with 1 5/8" or 1 3/4" primary tubes: 3/8" thick solid flange, 14 gage mild steel tubing (.083 wall), clamp marks polished, beauty welds on top and under the primary tubes, face of flange fully machined flat and de-burred, velocity cones in 3" collectors, header bolts and gaskets.

CHROMEX ceramic coating - $250.00
