Long tube headers
Is there anyone that makes these for the GS430? I assume the headers are the same from the GS400 and GS430 but I haven't looked to confirm part numbers yet.
I see that S&S closed up so did PPE ever come out for the 2gen GS? Looking to find someone that offers these for the GS430. Please post back if your aware of any places I may check. Need these for part of a project Im going to be trying out.
Thank you

Yes I have searched this section and already read about S&S....that does me not good. I got this thread when I used the search....If it helped I would not have posted
and yes I am looking for Long Tube headers. So back on topic can anyone direct me to something positive here
I checked Sikky and PPE and they do not offer for the GS at this time.

We are working on some right now. We are prototyping on an LS430 and will be test fitting on a GS400 after.
They are a 4-1 shorty, but longer than stock. In order to do a long tube header, you would have to remove the cats. We are thinking of offering high-flow cats as well as testpipes with the shorties.
I will update in a week or so when we are done and have some numbers.

Or is it possible to offer 2 versions of these. your shorty vs with cats and then a long tube vs with no cats

PPE im so excited to see the progress on these coming along. The headers are looking great! Can't wait to buy a set. What are the chances of these cracking like S&S? They definately look much better build quality. What type of metal are these and what are our options as far as ceramic coatings and price? Im sure many people want too know.

I think this thread should be renamed "PPE prototype headers in the works"
It is exciting to see progress here as I get plenty of PMs asking about options now that S&S is gone.
Long tube headers are not practical for these applications and may not produce as desireable of a result that properly designed shorty's can.
It would be very cool to have some dyno testing AND road testing of this design over the S&S. I was curious as to why PPE did not simply build SOME S&S style parts since they now own the S&S jigs and certainly have the skills.
Possibly they did not want to work with the tri-y design, possibly they did not like the drivers side tube pairing, possibly they prefered to start fresh and not produce another companies design...
The reason for the S&S tri-y design was me. The reason for the 1.5" tubes was me. The reason for the 2.5" collectors was Loren (I wanted 2.25"). The reason for the drivers side "wrong" pairing was packaging and due to the fact that Loren only had heat shields to work with for fitment. From what I can see above it looks like PPE originaly intended to use the stock cats but fitment has lengthened the design and forced a change. Everything is a compromise.
Curiously the brand new extremely impressive Ford 5.0 32v Coyote engine making 411hp uses the "wrong" pairing as well. Yes they also changed firing order but the reason for the above shows there is a gain and a loss to each design. When I first received an S&S I did a test that actually impressed me and indicated the "wrong" pairing was not going to be a big problem and possibly a good thing.
Bottom line is these new parts are GOOD news as the factory manifolds have the "wrong" pairing on ALL cylinders.
