Can anyone tell me whether this is the stock manifold for an early (1995) import Impreza STi RA ??

I need to renew the up pipe as it's blowing on the turbo end ... the up pipe splits into 4 before it connects to the manifold

Is this a standard manifold ? and can i still buy the up pipe only ?

Thanks in advance

No not stock and it needs the skip. It's not in great shape.

Pulled it out - it has already been welded in several places already.

I run it in a stage rally car with gems, my anti lag blew the gasket (which was as old as the manifold!) - any recommendations on a decent unit which will cope with the anti lag to replace it with ?

I've got next event in 11 days so i might try to get this welded up for now

Looking at that picture 1&3 look to be running leaner than 2&4 have you a parallel setup or is it just the way the pictures been taken. That manifold has had some fabrication so you would be as well trying to repair that one before putting a new/different one on cause it will need a map tweek.

Some more pics ...

How do you mean parallel - equal length or unequal ? i think it's unequal ...

A few people have said use the stock cast iron headers and get them ported/flowed, with a decat up pipe.

I think i will try for a repair, as no time for a map tweak before my next event

Yes alot of people use original exhaust manifold and get them ported. My mate has bought a set a ported them himself. Think he has a spare set if your after some.

The manifold in the pictures is unequal.

I meant parallel fuel rail setup not equal or unequal exhaust manifold.
