I have a CFM + which I think has the best flow. But in addition I have ordered an Iantake, from one of our members that is being made now. I will report out on it once I get it installed. The price was right and the customer service and communications are great.
I like my AFE's performance but they only sent me two stainless steel bolts instead of 4 like they should have so now the 2 non-stainless bolts are starting to rust. I have heard other quality control problems about AFE as well.
i have a customer in odessa, that gets every new thing we release and he's used about every manifold we carry, he said he's noticed the biggest difference w/ the AFE bladerunner, he had the CFM right before that one.
I've been looking for one too. Rollin Black Smoke can get you a heck of a deal, ATS makes one as well, and it wont void a factory warranty. Its now between ATS and AFE, the Banks is totally out because the bolts go straight through the manifold, seems like it would create alot of turbulence.
