Hooker sell them precoated in black or silver. Stillworth exploring as I don't need cats or any emission junk so if I can modify some OEM ones, even better if there under 100 bux or free

These speedway ones?

Hard to tell from the pics, but it looks like they might dump directly into the frame.

Similar but we're shorter, and I heated them and tweaked them in.

There C6-LS3 Corvette ones. Also seen a few of these LS1 Corvette manifolds used on buggies as you can cut off the flange & weld on some St.St V band clamps. There also nice as they have the bungs for the O2 sensors in them. There also a larger dia pipe so should flow better than the Hooker ones.

I salvaged the pedal out the Chevy truck, was going to cut the end of it off where the cable attaches & weld onto the LR pedal. Can then use the chevy cable complete

Nic, did you try the CTS-V Lsx exhaust manifolds ?

These, from what I've read are the most tucked OEM ones available and prob the only other option to the Hookers..... I bow to Nic's greater knowledge

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.
