the draw through on the intake makes sense to me
what baffles me is the the left and right join together at the bottom, but I only see about a 1 inch passage from the rear to the center ports and front one doesn't join; and has to blow into back pipe which in the end goes through that 1 inch opening
they should be like a double shorty header and exit bottom and top, bottom should cross to other side and top enters the turbo, what I see will not allow engine to run let alone build boost
