I have a 3 in i pipe and over the axle pipe and 3 in flowmaster tail pipes-that i really like.I also have a flowmaster 80 series crossflow(3in in and dual 3in out) and a Dynamax Super turbo(3in in and dual 3 in out)Which muffler should i use--which flows the best??

Dynomax hands down for flow

Dynomax.

Especially the ultraflow muffler. It's straight through.

I would think the super turbo muffler is OK for an unmodified engine, but if you plan anything that improves power and airflow, then it's going to hold you back. The ultraflow is definately the way to go, and should be a direct swap with the super turbo.

I've had two ultraflo mufflers and they both worked/sounded great. (3 inch and 3.5 inch)

The super turbo flows pretty good actually, they have flow directers insde of the and they are very quiet. I had a 5.7 TPI camaro with that cat-back and it was barely noticable with no cats

I had super turbos on my v6 mustang a while back. Kinda quiet at idle. But then when I got on it. It made me smile. Had that classic ford sound.
