hey dan,
yes that is an old evolution manifold..however it was discontinued around 5-6 years ago. one of the reasons we discontinued it was to that we can use a better collector and also the material these were made from were too thin often leading to problems like cracking. this manifold was replaced by the SR-series and then the new evolution manifold range was launched not too long ago.
we are unable to provide a manifold that is a direct replacement to the one you already have. if we provide you with either a SR-series/evolution manifold..then you will either have to purchase the suitable downpipe from us, or have one fabricated. we can also provide you with a universal turbo>fmic pipe to make the transition much easier. the new manifold do come with warranty and are pretty bullet proof. thanks!
