With side-exit 180 exhausts, there's a chance such a car could use (or copy) Hall's half-trunk-tub made for his 180s, especially if you laminated heat-resistent stuff to the front & bottom of the tub. The half-trunk looks like what was stock on the Miura and is a whole lot better than nothing.
FYI, I remembered one more drawback to 180s: there's a definite order in how that tubular jigsaw puzzle goes back together! During a tech session engine swap some years ago on Mike Harper's car so equipped, it took longer to get the pipes bolted back in than it did to swap blocks! Naturely, the pipe remover was not the pipe-installer and we (and Mike) had no instructions as he'd bought the car that way.
