Oh God not again!!
We had a set of custom Stainless headers kicking around this forum and the Lincoln LS forum for almost a year and nobody installed them. Finally they were sold back to an LS guy who did install them and said never again! Not enough room to work on anything. They were about $1200 new and dropped with each owner. I think at the end they went for $700-$800.
Here is what the other ones looked like:

BIP; How did you handle the EGR? Just plugged it off?
Thanks for making them. Do you have a price?

Ok so what is with the carrot on the string marketing plan? Are you going to mass produce these things or not? If you spoke to us (the direct market) we would tell you there are exactly three or four bolt ons that we need and would put up hard paypal cash for. Care to listen? I mean that in the nicest way possible, just curious why there is a completely different model's dyno results, albeit impressive and should be praised, are being shared in a forum that pretty much having nothing to do with it other than a cat and boost?

These are pretty to look at.I am surprised at the relatively low HP gain considering that they have deleted the catalytic converters.My RX7 turbos gave around 50 bhp increase when the catalytic converters were removed.
The real test of these headers would be to compareHP between the standard header with catalytic converter replaced with a pipe and your set up.

We are in the process of getting the EGR figured out, we want to eliminate it, but it all depends on how final testing turns out.
We would love to have a test mule for the S Type R beast, and whoever steps forward to make these headers happen for your platform, we would figure out cost with that party

Going back to my previously shot down story about the guy in South Africa that got 50HP on his XJR by removing the cats....
https://www.jaguarforums.com/forum/x...12/#post562567
Now, obviously if the cats were a little blocked up then that would explain a big jump in power when they are removed.
What we don't know about the figures from BIP now is what condition the cats on the test car were in.
Since it's at least 10 years old and probably >100K miles then we can guess the cats were not in the best condition to begin with.
If removing good cats is worth 10HP, what about cats that are blocked up? This is something we cannot qualify from the data alone....

Yes but it looks like Stainless Works who made the one piece long tube headers no longer have them on their web site.
Us Jag guys are just too few in number to make it worthwhile for aftermarket parts.
Thanks again BIP for doing this.
We have been waiting for Avos to get the TS blower out for several years and it may never see the light of day!

On turbo cars removing the cat or cats usually frees up exhaust flow enough to effect the factory boost control. So not only do you have the gain from no cat, you also get more boost as well. I have no problem believing he picked up that much hp.

Yes you are dead right,I should have explained but I forgot the STR is supercharged and not turboed.In any event the true comparison should be between no cat conditions,with and without the new header.
That is the way you should price out performance.
