Yeah, like he said. I told you earlier to get them gutted from Buckshot for $80, and make your own MIL's or get them from Trubendz.com for $20...Performance will be much increased and you will still pass the sniffer...Why pay 5 times more for less performance...Plus, with gutted manifolds, they are guaranteed to never go bad again. Can't say that about the non-gutted variety. But, hey, its your $ and your car...
