You might want to try Trick Performance. They are a sponsor of the sister site Performance Trucks. They have complete turbo kits as well as hot pipes and flanges for those that want to make their own kits. They don't make anything specific for the new Camaro but I am sure they can help you out.
Here is a link to Performance Truck(sister site of LS1tech): http://www.performancetrucks.net/for...d.php?t=469874
