If you are cutting the curve off the VX exhaust surely you will need a straight through tail pipe trim? You would then need a valance with the tailpipe cutout, unless you cut out the tailpipe hole yourself.
The tailpipe trim that I posted should come out directly under your bumper, without the need for cutting your exhaust.
