I am not totally 100% sure. I know that the primaries are 2" and I believe the collectors are 3"? But needed reducers to connect to the stock Saleen X pipe (Which I believe are 2.5").... And rest of the exhaust system.  I know that the primaries will be fitted to the collectors with the "Slip in" style.  They will not be welded.  That may be why they look like it steps down from 2" at the collector.

Ok. Chris at the shop said I will have my car back this weekend. He sent pictures of the 1 completed header ( pass side) and will have the drivers side done tomorrow. Still have to send them out for the ceramic coating, but nice already!

You're going with dual O pipes?

Not sure what a dual O pipe is  LOL

If your talking about those loops of wire loom, that is a sensor (I believe the lock out solenoid) for the 6 speed.  I left it long incase I did it wrong.  I actually left all the wiring I did longer than necessary incase I needed to go back and fix it.

When everything is proven to work, I will go back, and make the wiring "Pretty"  LOL

O-pipes go from one side of the headers to the other side. They use the exhaust from one bank to stop the intake charge from entering the cylinders on the other bank. This increases fuel mileage considerably because the car will no longer run...lol ;D

From what I can see in the pictures, they look to be doing a pretty decent job...on a job that would NOT be fun to do. Ceramic coating was an excellent choice, but even then those heat shields will be getting a workout!

LOL  Got it.  I actually stopped by there last Saturday and he said he has been trying to keep them as tight as possible (in working with my original Flange) so that I can easily take them in and out of the car if necessary without scratching them all up.

Im impressed.  Even though I have the tubular cross member in there, there is seriously a real estate issue still present.  I doubt seriously there would even be a possibility to put headers on the car with the OEM K member.  That thing was Hulking.

I am definitely interested in learning.  I purchased those Heddman headers (which did not work).  I never returned them, so I may chop them up as a practice tool...  Learn which setting on my MIG works best, pressure test them when I am done, Etc....

This Cammer Saleen is definitely not my last......  My interest in FE's and hotrodding is growing by the day!

OK boys and girls...,. today was good news.  Chris over at AC Carcraft gave me the call.  Headers are done and are going to be shipped out to get ceramic coated in Matt black.  I have the flatbed picking it up at 9AM (His suggestion) and it will be in my garage again by 9:15am  LOL  Below is 2 shots of the drivers side headers that he finished up today:

Pipes look great Jason!
Those boys have tacked up a few pipes before.
I guess muffler bearings would too much. ::)

SFI. I notice you have the SFI bell. But you have the socket head cap screws that came in the box installed.
That is fine for street only, but is a no go for the track. You must have Hex head bolts in the mounting holes. just an fyi

Good to know.  This car wont be used on the track....  just going to prowl up and down I-95 looking for unsuspecting Z06's  LOL

While the pipes are away getting ceramic coated, I am going to hook up the computer, install a throttle cable, and install the "circuit " Jay helped me build so that the tach would play nice with the Saleen Gauge.

I can almost see the finish line!

Videos of car running to come!

Awesome!  Car is back in the garage.  I have decided to get the car running before I send the Headers off for ceramic coating.  Have a place local that can do it , but wanted to see this thing fire up (waited long enough!)

I have a quick question.....  the FAST EFI Computer says to place it on an area that does not have "noisy Electronics "....  Rea;lly the only place I have left is on top of the fuse box on the passenger side engine bay.  Its a large black plastic box and its a flat surface, but I wasnt sure if fuses thow off electromagnetic noise?  Thoughts?

I already have everything wired Except for plugging in the EFI harness to the computer.  I need to just install the throttle cable and then I am done!  I need the throttle cable for the set up of the EFI as it asks you to hold the pedal down at full throttle wile setting the initial program.

I doubt the fuse box will have any significant noise, unless of course it has any electromechanical solenoids, which I doubt nowadays. 

Also, make a promise to yourself now to pull those headers after you get it running, you'll want to get those coated for heat management.  It makes a world of difference.  If I remember correctly you were sort of on the fence, don't let the fun of the car talk you out of it once it runs! :)

+1 on the header coating.  Also, just for safety I put a big capacitor across the power and ground connections, right at the EFI box, to minimize any noise issues.  This has made a world of difference on the dyno, and also on one of my cars.  See the link below:
