So the poll is leaning towards 2.5" My Y pipes are 2.5" He will just have to cut the spot where it Y's in to collector. I am sure he can expand the 2.5 to the 3" muffler.
If 2.5 can support what I have/could have with room to spare, I will contact the muffler shop tomorrow.

I don't see a real need for true duals and a cammed engine, w/ stock heads. IMO, a 2.5" true dual setup isn't going to outflow a single 3" exhaust setup. And a single exhaust run is going to be cheaper.
IMO, 3" true duals < 4" single.
My setup: 1-3/4" LTs, ORY, SI/SO chambered borla xr-1, corsa 3"-3.5" tip. Flows its *** off. Could be had for less than $1k, depending on what you want to run.

In my feeble mind, 2.5 duals = single 5" pipe, 3" duals = 6" pipe.
This Magnaflow has an X built in. But for good measure I can have the exhaust shop put one in.

Granted, its not quite an apples to apples comparison among them due to the dynamics of the gas through the pipe (heat, behavior of the gas near the pipe wall, etc) but its a rough comparison for discussion's sake.
But in short, yes, it can be safely assumed a dual 2.5" will outflow a single 3", and a dual 3" will outflow a single 4". Now the effects of one size versus another is a whole other conversation.
