Yes the headers will fit. The flamges from the manifolds are 30 degrees further to the outside than on the ISF. Otherwise, the manifold pipes are identical to the ISF
However, once you decatt your primaries, you might ( and I use this mildly ) get a CEL that retards timing into failsafe mode, or just get a CEL without any retardation.
since I have not been as active did you ever test/try that Apexi Neo?
if you looked deeper, you'd have seen that the engines part numbers are identical too.. and last time I checked, they are not .. PNC is not the Part number.. the one under "details" is.
Ah, now you've pointed it out, I see my mistake - it's only part of the full part number - thank you.
Interesting to see there's two versions - 8020 and 8050 for the same part, both with quite different prices.
Is one anything to do with California's CARB or whatever it's called?
PPE Engineers have mentioned in an email to me that they will have something for the GS460 by end of this year. It is still a long way to go, but at least we will have something that fits our cars with I hope good HP gains.

still waiting on the headers... no, dont think it will fit the 430 since the headers seem to be different. Heck I dont even know if the ISF headers will fit haha...
Old thread but has any GS460 owner successfully ran ISF headers or have any updates ?
Ive noticed that the GS460 runs the same log tube header design as the 357HP LS460awd. The 15 HP loss must be due to the single air intake and 2-1-2 exhaust.
