3" DP & other exhaust mods?

[Black_Mamba]

Thinking of getting ported exhaust manifold, a 3500 ported upper intake manifold to match up to a 68mm Billet throttle body, a JET Performance 69108 MAF (from Jegs), and a 3" down pipe.

Will most likely need a high flow cat or no cat. But as of right now, my exhaust set up is all stock, only mod close enough is a k&n cold air.

Let me know what you guys think.
