Which Flows More?

Technically speaking a dual 2 1/4" system has more flow area (7.95" for the dual 2.25" pipes -vs- 7.07" for the single 3.00" pipe). But I'm no airflow engineer so there may be other factors involved so I can't tell ya that it'd be better than a single 3". A lot of people seem to like the 3" single shot systems. There aren't many people that run less than a 2.5" dual system as far as I know, but I do remember hearing quite some time ago of one member that was running a 2.25" dual setup on an 11 sec TB.
I just replaced my older-than-dirt ATR 2.25" stainless cat-back with a 2.50" Torque Tech dual setup. It was getting pretty nasty looking, it was at least 12 years old and the welds in the y-pipe were rusting so I decided to step up.

These cars defy the laws of physics so it is hard to tell. Turbo TR's car probably went faster because the turbo liked the added restriction. Are you running a catalytic converter? Stock?
IMO it went faster because of less restriction. Uncorking the 2.5" Hooker setup at the track also provided a ~ 3 mph gain, consistently. 126, 126, 126 mph capped then 129, 129 mph uncapped, same night. A week or so later put on the 3" SS and went 129, 129, then uncapped it and went 129.5 
Clearly it flows better in my case. Plus it weighs alot less.
Just my results. YMMV.
