EDIT: 951 exhaust manifolds...see last Post/Poll
Highly considering making a new coated-stainless exhaust manifold for the 951, to Rennlister's specifications. Manifold will have v-band clamps for easy fitment/alignment, provisions to control "walking" since stainless moves around quite a bit, and both stock & Tial flanges for WG's.
So, If I can provide such a header for under $700, tell me what you want please.
Here's a sample of some of my work: I work with Boostlogic in making my 928-turbo system & other manifolds for them.

can you elaborate on your 4:1 request & long runners please?
Yes, I know what you mean, but why you request this over the tri-Y design? Thanks!

To maximize exhaust scavenging in upper rpms. I want maximum power, not torque
I could never justify the cost for a new exhaust manifold if it still kept the OEM design.

Ah here is a perfect example of the design I'm looking for:
With long primary runners in the correct length maximum high rpm scavenging can be combined with "tri-Y" low range torque.

I was thinking: 4:1 medium-tube header, professional-merged collector, V-band clamped to cross-under pipe & WG provisions & flange to turbo, two O2 bungs: one for factory, one for WB. Cost could be as high as $800 with everything, but hopefully cheaper. will have to build one first for pricing it out with my manufacturer.
Anyone know what ID's the primaries, collector/cross-under pipes are? For the Power most are makign who will want this manifold, I was thinking 1-3/4" primaries merged to a 2.25 collector. I think factory is 1-5/8 & 2" collector. Can anyone correct me?

I'll have to use a flexible joint, but they're not restrictive when placed out from the bends (turbulence & higher velocities on one side of the pipe).

where's the jawdrop smiley?????
are you going to make more than 1 application? as in, one made for more street-driven "normal" cars, and a high-end one like Duke described? or will it all be high-end-of-the-rpm-range ones?
cuz i can always turn my 951 into "not normal", lol.
