they were made by an exhaust shop for around 300 bucks from memory
they wont give you as much power as a good set of equal length 4-1 extractors with primary length and diameter tuned to suit your cam timing, think of them more as headers than extractors.
i had a ride in the car these came from (and my engine came from) and it was definately not lacking power.
build quality is good, when would you like to have a look at them? i will be at my mate's house tonight if that suits you.
