I would think you would be okay... most people i know do 2.5 duals with an unmodified engine.... my guess is it would help flow better

Dual 2.5 would be better.

Yea thats a big exhaust for that engine. Not ideal. A single 3" would probably net you more power under the curve, and definitely help down low. Thats what I would run with a cut out that you can open after you get out of the hole.
