Single cat vs. duel cat

I'm looking to add a set of Hooker 2055 Headers and a SLP catback to my Formula. Would a single 3" Magnaflow converter flow better than the factory duel setup? I know the 3" would give me more clearance for subframe connectors. Thanks for the input.

"Dual" The exhaust itsn't fighting itself

IMO Single 3" cat. Much easier to pipe and cheaper than buying two cats and the assoicated pipe.

L.O.L. You got me for dual ,I got you for associate. The single large cat setup would look better I.M.O. because it would'nt hang below the rocker panel like the factory dual setup does. I found a site (justmagnaflow.com) and bought a 3" in & out converter with air tube for $64.00. Chris
