HSV 340 Headers on US spec SS

[teetopz]

Can anyone confirm, or deny, fitment of the HSV 340 tri-y headers on a US spec SS (VF2)? They seem like a decent bang for the buck performance mod, but I don't want to get a set shipped over here if they won't work. Thank you.

They'll fit, just ensure you are getting the 'genuine' 340kw HSV headers, as the header outlet has a larger diameter than the 317/325 HSV headers which look identical.
Not as many 340 headers manufactured, so they sell for a premium.

Thanks. On another site, it was mentioned they wouldn't clear the LHD steering shaft. But you're confident they will? Also, these are the ones I'm looking at. The outlet appears to be the larger HSV 340 size, correct?

They appear to be the correct headers. I'm not sure about the clearance issue with the LHD steering shaft though...

clear the LHD steering shaft.

That was the first thing that came into my mind but I don't have the answer.

I didn't think of that when I first answered...

Googling images they don't look symmetrical so I would guess they wouldn't fit

@teetopz ........ you could ask this of GMSV (which was HSV) in their contact details ............. https://www.gmspecialtyvehicles.com/contact-us

But I wouldn't be holding my breath for answer. But you could get lucky. No harm in trying.

Thanks for all the replies. I've sent an email as suggested by Figjam. Probably going to pass though.
