Nope. Didn't try them. New, they are $149/ea. I don't see the value. Also, good luck finding the down pipe flanges. I had them custom machined for the Hooker manifolds.

Clarification: I had custom down pipe flanges machined because the people who wan't Y-pipes didn't send me their flanges that came with the Hooker "cast iron" exhaust manifolds. (Matt & Matt excluded) The aren't available. Also, the flanges supplied by Hooker are investment cast stainless. Both have 2.25" tube openings.

Does anyone have a comparison of engine length for the 3.9 vs LS9?
I have a 3.9 with ZF in my 109 that is getting long in the tooth. My chassis is a 95 disco so I can move engine mounts and change drive shafts if needed
thanks

These are the manifolds I used on my IIA crawler after trying several stock LS options. The clearance is about 3/8" on either side. I built the Y-pipe out of s/s mandrel tubing crossing under the bellhousing area and backwards on the passenger side since I'm using custom Currie 9" hi-pinion axles and a flipped Dana300. I personally can't stand most aftermarket headers. They are thin, noisy, rot out too quickly and many use the flat paper gasket that always leaks over time. I had a set of Sandersons on my 4.3 that burned out in 6 months. They refused to replace instead offered to sell another set at $400. I modified a stock set of s/s manifolds. Those were still righteous after 12 years of abuse.

Only 'value' if you can score some cheap on Ebay.... as I noted, was just throwing out an option that may work.

The Hookers are advertised with st/st flanges in the kit.... correct ?

Value is in a product that fits well, works well and is designed to last +200k miles. It's hard to beat a GM engineer at their game. The only headers that would come close are heavy gauge s/s. The Janspeed s/s header on my 2.4 L6 240Z comes to mind. They were last produced in the early 80's. A comparable header today would likely cost +$700. The exhaust in my LS1 IIA is all stainless. Total cost was somewhere in the $700-$800 range. I did all the design, fitting and welding so I absorbed the labor cost.

I tried them and have that set sitting on a parts shelf. They were too wide for my 94 D90 chassis.

The hooker manifolds are very good quality. plenty of other variables in this swap so I'm happy i just went with them.

A word of caution to any one doing this. Pay very close attention to the fuel hose to rail connection. Not long after i posted that video mine sprung a leak. its sprayed gas all over me and burst into flames. I got burned pretty badly and lucky to be alive. I hate to think what would of happened if i was driving with my family in the truck when this happened.

I've since ready several stories of fittings failing.

Oh Haha I was super jealous! Yes it kinda looks like I am on that same path. I still have my place there. I will be back in the spring to assassinate some gobblers! The guys in here can help you with your question. Someone will chime in I am sure.

These look like they dump too close to center. Might interfere with the engine mounts.

I thought that too but there st/st & easy to modify. Might make for cheap alternative with a bit of work.

Spoke with the folks at Lokar yesterday and they said they will be releasing a 6L80E specific shifter after the new year that will allow for moving through the full range of gears rather than just PRND. They told me it was shown at SEMA however I have yet to find any reference.
