The second one has a twin scroll up-pipe. Why don't you get an RCM one it'll last that way. I have one on mine and it's really really good.

On second glance it's just me being a dunce both are single scroll.

Why are you wanting to change the headers is there much need unless going for big power eventually .

Both of the ones you are looking at are equal length headers just in case you didnt notice.

Must be un equal for the flat 4 burble IMO.

Laterial / rcm three bolt headers are the only choice for quality if it were me

A lot depends on budget/spec.

Under 400 BHP go for Harvey ported headers with a matched up-pipe for your turbo Jaffa also does a good job of porting headers (not sure if he ports the collectors though) but does not do the Up-Pipes (as far as I know).

Over 400 then look at the 3 bolt headers (GT Spec) either from RCM, Lateral or Advanced Automotives Harvey can also supply these with a custom matched Up-Pipe which will iprove both spool and torque over the std Up-Pipe (also at a good proce and DEI heat wrapped).

One other option which I keep toying with is a set of 2 bolt up-pipe tubular headers from Williams Motorsport (Andy built my engine) purely because they are so much cheaper (Around £200) eBay Link

I know the 2 bolt up-pipe can cause issues but you could almost buy 3 sets for one set of RCM/Lateral!

For the power i want RCM one is not worth it as i am running a standard STI 3 gearbox and a TD05 18g..

My exhaust manifold is leaking at the sleeved piece where there are supposed to be sprigs pulling them together.

Not sure on what the equal headers sound like, but yes i do want to keep the burble..

Would love to spen that sort of money but i can not really afford them and as i am only running a TD05 18g i will not be running big power at all.

That is more of a price i am willing to pay, i wont be chasing big power as i have a standard STi 3 box and TD05 18g, would like to be chasing big power but just can not afford it, is that a Andy motorsports manifold?? On his stuff he normally puts his logo on top of the page, i have brought some stuff off him before, he is a very nice guy..

If your only using a 18g just us oe & the porting makes very little differents

Cheers CJ, only reason why i was going to use another set was because Simon advised that tourque figures are noticably lower on standard headers..

If you got tubular get three bolt or don't bother . The choice is yours though
