Is their a Borla Atak CAt-Back or Axel-Back system I can use without and Keeping the DD configuration and slats ?

It wouldn't be an up grade but any good muffler shop could weld the tips to what ever you want.

Id say if you are going for loud, Id look at Corsa. They are the only ones I know of that don't resonate terribly. The idea of welding the DD's a new muffler is good. Since the C6 Callaway exhaust is out of production now Id be hesitant to hack it up though.

Any thoughts or experience with Billy Boat axle backs, specifically the PRT model?

Sorry I have no experience with those.
