Yes as far as a dual exhaust goes 2.25" or even 2" would be adequate. The stock tips can be used and the easy bolt on ability will be included.

I made a run today with just the exhaust and everything else stock.

The results were 14.400@94.649. I'm pretty excited about this, more for the trap speed improvement which has never been over the 93 mark.

I think with a little improvement in the intake and traction I can see a 14.1 or hopefully a 13.9.
