I've been asking around at local exhaust and manifold manufacturers and they want stupid money to make them... Sacha is the way to go until Sam gets his kit up and running.
you can do the kit for cheaper mate if u scrap the parts together i.e ebay turbo, civic rad , cheapo fmic and homemade piping etc etc etc ... but im sure a lot of members on here would agree with me when i say its better to buy quality and do it right first time or it ends costing you more in the end and a whole lot more hassle.
