now that i picked my muffler,im wondering if i should go 2.5 or 3 inch,dual out the rear,not any real mods yet, but air intake setup soon,the exhaust,headers,and a mild camwill be soon,i just dont want to lose to much pressure going with 3 inch or will I?
Definitely 2.5", 3" is too big for dual.

Yeah, I have 3" straight through. I don't know if it made a difference or not. My ETs are still pretty much the same.
even after i get the headers, cam and air intake? 2.5 is what i was thin king though
Since you are N/A, go 2.5"...

i am running shorty headers wioth factory y with cats,single pipe in to duals out to thr rear sides of hitch.
2.5", need a little back pressure. 3" and you would kill the lower end.
