Back in '01 or so Borla told the Stratus group that they'd have a catback system ready within "a month or so." It took over a year and pressure from mopar to get the actual part produced. The system now sells for about $650 and is marketed as both the "Borla catback" and the "mopar performance catback."
If Borla manages to produce a system for the Crossfire in less than a year I'll be impressed.
