Our preliminary understanding of the space limitations has us looking closely at the Flowmaster Pro series or DBX series, both of which were previously marketed under the Hushpower brand. Also, the Sebring Tuning 6" x 14" found on the black Rapier car because that's basically our configuration, although we haven't been able to hear what that sounds like. Would be awesome if the gent that owns that car now could record something for us. . . hello. . . anyone there. . . anyone? 
In any case 6" round x 14"-ish in length is what we believe is roughly the space we have to work with, maybe a little more.
A rep at Borla also recommended the XR-1 Universal line. They have something that roughly fits those dimensions, but again haven't "heard" them.
More to come soon.
