Don’t use the jap speed ones, the flexi’s will split.

Is the old GT Spec1 manifold now discontinued (they were only 2-bolt for the up-pipe, weren't they?)

Is the GT Spec2 manifold a 3-bolt...?

also interested in this thread, I have a hawk sti with forged engine running a vf43 @ 350bhp, I will be looking at getting around 400bhp from it with a different turbo and I would need a decent set of headers.

cheers

GT1 manifolds 2 bolt) haven't existed for possibly 10yrs or so now albeit i am aware of a few "copies"

GT2 kits are all 3bolt

we do specific Harvey Smith 'trick' up-pipes for both types as well as other offerings.........

Yeah, I have one of Harvey's (RIP) last batch of GT1 headers with his latest slip-jointed 2-bolt trick up-pipe, suitably sized for my TD05H 20g.


When they fail, I'll no doubt be in touch for the GT2 headers/3-bolt trick up-pipe...
