Kyles post to me about back pressure myths boads against the pipes being too large, not enough 'tow in the flow' for them to work right.
i'd say 2.25" if you'll be doing a full true dual exhaust
I didn't want to go off topic in the other thread this was brought up in, but engines needing back pressure is just a myth.
Here are a few threads which explain the reasoning:
Backpressure
exhaust instead of lift kit
good idea?

hey i never said live by it, just a quote i found that was on my side.
@rottidog i would never put that big on a 4cyl or a tiny v6, only the big v6 and the v8s.

there is a limit as to whats good & way over board as to what can be done to a basically stock 4.3 in the ways of exhaust, power train & drivability... 2.25" exhaust on a single in/dual out is nice & as the blogs say ala Kyle, it's acceptable for a true dual exhaust as well
