No twin scroll available.
2k might be cutting it fine.... exchange rate isn't great at the moment. Manifolds alone are 1100, plus postage and taxes etc....
Videos and pictures of it are all in my build thread

Twin scroll but it run external gates, the manifold is something designed and made for Pat from scoobyclinic. Will dig out some pics when I'm on the laptop

That was his previous engine, I'm assuming his new one has uprated cams etc, but I guess I should let J answer

Just had my HKS equal length headers fitted today on my STI hatch. What a transformation a lot smoother power delivery and it feels like it wants to rev more. More like the evo8 I just sold before buying the sti hatch.

New headers without mapping on STI Hatch? I'd get it mapped pretty quickly if I were you!

Better flow, would mean it will be running leaner. If it blows will Alan do you a free rebuild?

I thought when engine is under any load it runs open loop so will be running off the sensors such as maf and exhaust sensor. So how can it run lean.

So the so-called equal length manifolds sold by RCM etc are nothing of the sort and would offer little if any peformance improvement over standard unequals?

Never used rcm so can't say!
If anything they would crack and fall apart the same as the normal ones anyway

So I guess it's Killer B re-mortgage time or leave it as standard!

I stilk think you would see some gain from regular equals, yes the metal is not as good as the killer b's but much easier to weld up than unequals. Reason being unequals always crack near the collector which is nigh on impossible to get to

Yes, that's where my first set of GT spec G2s let go and were unfixable. I'll wait until the second set goes pop (2 years and counting) and then give the equals a try.
