Hey guys, I'm really not sure what is going on here...
I'm just asking a simple question - as if the exhaust that you are selling is made out of T-304 or T-400 and the answer is that I can not tell you because I spent too much $$$ in R&D.
What R&D? The properties of these materials are well known so there
is no reason for somebody (who doesn't create a new material) to spend anything for R&D.

Jason- you mentioned that "come up with a real product that they can stand behind. "

What do you mean by that?
There is no warranty of any kind implied in the description so what does that means?

It may seem like a simple question, but consider this: What if NOBODY had figured out the correct material to make the exhaust out of in a Miata? What if the materials used in other cars weren't cutting it? What if mild and stainless steels just melted away? The material properties are well known, sure, but what properties are the ones we need? Nobody can concretely answer that question - the ONLY way to ensure that you've made the right material selection is to order in a small (read: expensive) quantity, put them into cars, and get them tested. I've spent the money to have prototypes made, and I've spent money and time testing the studs and having other qualified people test the studs.

I'm not going to put a product on sale that I can't stand behind as a fully vetted item, but at the same time I will take steps in order to protect the financial investment I've made, as well as the time I've invested into that vetting process. I'm not sure what else I can say here - the alloy I use works, and I've proven it works, but I'm not going to divulge which alloy that is.

Max Power,

Please check out this thread if you want to read about what all has been tried.

What does it matter? The studs work.

Confirmed today, these are 100% for sure getting made. Tenative ship date is July 15th, 2010. I was able to get the threads rolled vs. cut as well, which is sweet.

$105 shipped GB price extends through Monday evening of next week, then the price will jump considerably. If you want them cheap, get in on it now.

Nice, the money is in your account for TWO sets.

The edit window on the OP has expired but we have 9 orders, only 3 more slots at the $105 price.

In for a set. Sending money now.

TEN, we're good to go Sav! You go girl!

This group buy has expired. If you got in before the date, congrats, you saved a whole pile of money and helped bring a much-needed product to the community. Expect your parts in early July.

For the rest of you, these are now available for preorder for $159 + shipping.

Hooray!

Any word on these puppies yet? I took all of next week off to do my install, these will be kinda important. :-)

If they are delayed, what's a good source for 10mm studs I can get quickly for temp install? Just so I can get everything in place...probably won't drive it until these arrive.

I was expecting them last week, apparently there was a little bit of retooling needed which delayed things slightly. They are scheduled to leave the manufacturer by the end of the week, which means I should have them Monday.

No hard shipping date until I have them in my hands, though.

All group buy orders shipped out via USPS today. These kits are now IN STOCK for $159.

Awesome, thanks!!!

I got my Inconel Studs in today. They will hopefully be installed sometime in August once i am done moving.

Got mine toos!

Thanks, Sav.

Drilled and tapped my manifold, drilled the flange on the T25, and got the studs in today... very nice pieces Andrew.

BTW, no probs with the hardware fitting on my T25, just need to have enough brains to start the nuts on when the turbo isn't all the way down the studs.

Awesome. It had me a little scared. The first batch of Stage 8s we got were 17mm wrench heads, obviously no way those were going to fit. I called Stage 8 to get the 14mms I'd gotten in the past and they said they don't make them anymore due to a supplier change. Glad to hear the 15mm heads work out.

Im not near the car in any way at this moment and I need to time-sert my manifold. Which end of the stud goed into the manifold (long or short) and how long is that end?
