    Mufflers permitting, dual 2.5" ( mandrel-bent, of course ) will support 520 HP with NO restriction. 3" is just loud, drawing cops.

    Hey! I was tbe first to say the Borla brand mufflers! I want Prime Rib dinner!

    And for the record, there is a pair of pre-cats, a pair of mufflers and a pair of resonators under my wife's CTS-V Sportwagon.
