alright fellas. last night we finally got the finishing touches on the headers. everythings good to go! sounds great too.
butt... heres the problem, the picture i took with the dimple; IT STILL DOES NOT CLEAR THE STEERING SHAFT!!!! F#%^ MAN!
my friend said he might have to take the headers off again [ driver side ] and from what it looks like, the heatsheild for the steering shaft. i mean dont get me wrong it drives and it turns but, you'll def feel / hear that grinding noise from the steering wheel.
anyone eles that got in on the groupbuy putem in yet?

Sorry about the issues. The little heat shield tacked to the steering shaft must be removed. A cut off wheel or dremel tool works well.

yes if its a bad rub, on my final (3rd header) i got in i had a minor clearance issue, i bent the steering rack shield as much as i could without removing it and then i let it rub for a few days knowing it would eventually wear a grove in that would make its own clearance so my car is fine now. i do love these headers once installed 
its not that they sell headers without testing since you obviously arent aware of the info why make the derogatory comment since YOU dont know what your talking about
they initially tested on a 2001 LS430

but then did a retest on a 2000 GS400

they bought the old S&S headers jig and proceeded to make them better, IMHO they did a much better job. From what i know, they had a couple of ****tards working for them for a few minutes who messed up alot of their 1st batch of headers and then from what i heard tried to go make their own header company which failed (shocker).
i had a theory which i still kind of hold true too till someone shows me otherwise.... the 1st gen PPE headers didnt fit the GS400/GS430 very well at all (only with steering rack clearance issues) because they were test fitted on a LS430, 2nd gen of PPE headers fit much better for the GS400 (although a few members still had minor issues) because they were designed ON a GS400 they never seemed to fit the GS430 very well because they never tested on a GS430. they used the mock up of the the LS430 as the design for the SC430/GS430 but the unkown factor is would the steering rack have clearance issues on all 3 models and it seems the finalized answer is yes. this quote should help clarify what i meant
according to my theory i think if they would get a GS430 on the rack they would have to tweak their design for the GS430 due to the steering rack as im pretty certain the 98-00 model used a different steering rack then the GS430 did I have said these many times now but i wanna reiterate it Paul's customer service has been absolutely one of the best i have deal with from a business in a long time. keep in mind they are losing alot of money having to remake/reship these headers to us for free.
i do honestly hope they get this worked out before the V8 header option goes away from us all but i think they need to get a actual GS430 on their rack to do this
thats all that needed to be done Paul? i dont even have the "dimpled" header and mine didnt have to be removed just kind of notched.....well maybe my theory is wrong lol

hopefully the gs design will also fit the sc430s.
i haven't seen an sc manifold yet. Are they the same as the ls, gs or completely different?
according to the oem part number, the sc430 shares the same manifold as the ls430 and gs430
that is my understanding.
Worth noting is the gs400, ls400 and sc400 all have different manifolds with the gs400 and ls400 having dual tube tri-y type and the sc400 having a single tube design.
The 430 engines went back to the single tube design for early catalyst light off and have the same flange locations as the gs400 dual tube design.
The unknown here is the ppe design for the ls430 had interference with the steering on the gs430s necessitating a redesign. Until a set are tried on the sc430s it will not be known if the gs design will fit the sc430 and the ls430 design is almost certainly not a fit. Although it is possible that the gs design will fit the ls. If the gs design performs as well as the ls design it may make sense to build all of them to the gs configuration.

yikes! I didn't realize there were so many variations. We did the ls430 and the gs400 prototypes. The steering shaft on the gs400 try-y design was way different than the log manifold of the ls430.
So the ls430 headers we did should fit all the 430 cars it would seem since they all use the same stock manifold, yes? And the gs400 headers will only fit the gs400.

looking at diagrams of the different steering gears in the different models/years. It looks like the ls430 headers should fit the gs430 too, but the sc is steering gear box is a bit different. We will have to get one in to take a look.
For now we should have the gs400, gs430 and ls430 covered.
We are starting on the is-f this week, so the sc cars will have to wait a bit.

I just unboxed my headers today and for some reason I don't have a dimple on my headers.
this is supposed to be on the driver side header and the dimple is supposed to be on the left side right??
also I am missing a 10mm bolt listed on the whats included list. I have a 430 btw

Is that a picture of your header? That is the SC430/GS430 header. I will get a 10mm bolt out to you. Please email me your address: sales@ppeengineering.com

I just stole OP's pic cuz I was looking for the dimple and I couldn't find one.
But here is my drivers header and I don't see a dimple on the bend before the collector.
Also the bend in the tube where the dimple should be is different than OP. His is 2 smaller pieces welded together with a dimple while mine is just a bent pipe.
so am I just looking wrong or I got sent a wrong header.

We have prototyped and tested all of our designs on cars here at our shop. We have had more than one GS430 come in to prototype and test fit over the 2 years that we have been making these, as well as SC430s (same header). We have customers here running for 2 years with the heatshields removed with no issues.

The factory manifolds have a major restriction around the outlet, it is a log style manifold. The restriction in the manifold causes them to get very hot. Our design is much larger at this point and runs much cooler. The headers are also ceramic coated which is a very effective thermal barrier. Removing the heatshield around the shaft will not cause any problems.

here's another picture of the headers for those who are interested. And I was sent an incorrect drivers header, but Paul from PPE has already contacted me and is in the process of working this out.
