if you give me a free set of your LT1 longtube headers i will drive my car all the way from IL to you so you can do testing for a y-pipe
but if not i would be interested in buying a set without emmissions hookups

I was going to order my Hooker LTs from you after the first of Jan, but I think Ill wait now and see how these turn out. I would not need emissions. The Y pipe definately needs cutouts though
Also, if you dont want to use simple's car, I could also provide an Illinois car for testing in exchange for a free set.

also i think the slip fit would be the best solution. that would be an oversized 3" on the collector to fit over the 3" y-pipe instead of a slip where the 3" y-pipe fits over the collector...correct? that way you dont choke the flow when the exhaust enters the collectors.
you said O2 bungs on the outside of the collectors?? i think bung placement should be towards the inside of the car so the wires dont have to be routed around the hot collectors.

Exactly what he said. If you have to use a 3-bolt collector flange, make 'em thick so they seal better. If you make a header that is well built, makes good power, is fairly easy to install, has good plug/wire access, good ground clearance, has provisions for O2 sensors/emissions equipment, and is reasonably priced; you will have a real winner-and many customers. This is a very tall order, and for everyone's sake I wish you luck.
If you can make the headers as stated above for the $511 dollar price tag with the 3-pay plan, the only problem you'll have is keeping them in stock

I think the 3 bolt flange would be the best and then offer a ypipe for it. A lot of people are now going the true dual route and the hooker lt's make it super easy.
Another vote for emissions stuff as well!
Good luck!

We should be getting a car shortly for the test fit. After we make a few changes, we'll start manufacturing the headers, After we get the 1st batch, I should have some pictures.
Thanks

do the right thing for the environment
Jet Hot-
Do the right thing and build them with emissions hookups. Leave it up to the the buyer to disable the functionality. The decision shouldn't be any more difficult than that. Also, if you're going to do flanges, the flanges should be very thick so they can be torqued tight enough. (Picture a turbocharger and the downpipe flange) I think some of the other flanges are too thin and that causes the flex during temp fluctuations and eventual blow out of the gasket.
Also, ypipe with cat(s) that fit both types of cat-backs (single and dual cat). I'm waiting until January now....

However, on the issue of flanges... I think 3/8" is plenty thick. You can only make the flange so thick; if they're too thick, you'll have a problem getting some of the header bolts to go in. I have Hooker shorties right now and 3/4" long Stage 8 locking bolts, and I can barely get some of the bolts started because they hit a primary tube. Plus, if the flange is any thicker than 3/8", a normal 3/4" header bolt don't thread into the head very far; then longer bolts would be needed and you're back to the first issue I mentioned.
Also, I wouldn't know the feasibility of the headers "bolting up" to both single and dual cat exhausts. It would seem awful difficult to me to make an efficient y-pipe with good ground clearance to bolt up to a single cat exhaust. Personally, if I went to LT headers, I'm getting duals too

I am having a band clamp and lip welded on mine. The 3 bolt flange sits too low. I will also band clamp and bolt at the Y.
I am making a custom 3 inch ORP and custom 3 inch Y w/cats. Will be bolt in/out
Unfortunately, just the parts for this are running over 300$ so far...Car sound Cats, JBend from SLPOnline, VClamps + flared ends from Airflowonline.com.
BTW, the headers are awesome!
