The Fab9 Elite is a two part design with a plenum that tapers smaller towards the opposite end to the throttle body. The 10 bolt flange that allows you access to the inside of the plenum looks symetrical to me, so in theory you could rverse the plenum/throttle-body orientation relative to the four runners.
This reversal idea is an interesting possibility for Monty, with the throttle body at the opposire end and now facing to to the rear, the plenum taper works with Monty's natural bonnet taper, rather than against it.
However, the next challenge would be having sufficient space to fit an air filter to the now rearward facing throttly body. TBH, a forward facing throttle body would be a superior setup for a number of reasons, so it's really down to the bonnet to throttle body clearance, or just fixing that issue if it arrises with an expensive Supersport bonnet scoop.
