Backfire valve? Intakes look pretty damn nice.
The first batch of manifolds have been completed. We have standard 2x4BL and 6-71 Blower manifolds in stock. We will be contacting and processing orders next week for those of you who have contacted us prior, once we take care of all of you guys we can process any new orders.
Special thanks goes to Rich Rojeski and (Brian LaBombard "marketing" )

Well that other fella from down south claimed it was worth 100HP more over the 881Man, every time I view these pics I think to myself "I gotta sell some stuff and get one of these" .
Would love to hear of any performance comparisons .
