best place to ask neil would be a subaru forum, last time i had a look there was plenty of information as to which was better with most gains .etc
i imagine it would be very brand dependant as to which is the most effective.

Good power gains to be had, but there are problems with them cracking if they don't have flexi joints (much more expensive) and they all look pretty
deep, will lose the rumble if you go for all out power with equal length one.
I've heard a basic match porting job on the standard headers can give up to 30bhp which is the way I'd go..

Hi
Im pretty sure that the Rigolis still use a modified stock header on their drag car.
Im pretty sure from what I have gathered is that the headers are usually larger in diameter, that will move the powerband up in the rpm range.
I might change the up pipe, there seems to be gains in that area with no down side.

I got a power up pipe on my car, however I made one for the splitty that is a little shorter than normal, with a different angle to fit under the
tank. This is where there is alot of difference in port size. big to small to big again, with no smooth transition. I looked at all the ports on the
headers and they were already matched.
