So the needswings dual CAI that comes with the V8 MAF and 74mm throttlebody is the best start then. the only remaining question I had about that was how does it pick up air, the filters are straight up sideways. As for the exhaust, I like the dual down pipes and secondary cat delete of TVT. if magnaflow can do that too, that will be another product I am sure on. I also saw a member on here with a dual CAI that made a Y on top of the intake manifold and ran one big pipe to the TB from two in the front. I'd love to know more about that.

I think that the way the NW dual CAI tubes collide at the back might be less efficient than the angling Y pipes shown in the links. Plus, with the filter in the tubes, you could have the devil horns which I also think would be better. I don't understand how tubes running sideways at the back and in the front could be better than something that mostly flows longitudinal. plus the ones in the links just look brutal. I am enamored with that look. a big Y just stuck to the top of the engine.
