I may be barking up the wrong tree here but are the forester ones equal length? They would be a cheaper alternative to tubular and with some porting im sure would give good results???

I await to be wrong

At that power level -
Contact Harvey for some Tubular Headers GT 2. Get him to wrap them

They are unequal length - but you wont see less power. Or perhaps the tinyest un-noticeable fraction less.

Loose rule of thumb. As every car is different. Is port the OEM ones below 400ish and go for tubular ones with a car speced over 400ish.

Perrin. Got em on mine. Scream like a sports bike when on boost. My mapper said in his opinion they were every bit as good as GT Spec if not better.

You do need a twin scroll sump for them to fit though

flexi joints = W@nk.....

advanced automotives in bristol do RCM parts slightly discounted.
