The center exhaust looks strange underneath. I looks like the tee to two mufflers still exists and they made a plenum that feed to the exhaust outlet from the two mufflers. I just don't get this tee into two mufflers thing. I would rather have a single pipe.
Good chance there might be space to tuck it up a bit more all depending on whats underneath. But aside from that looking at the Civic from the angles we would normally on a day to day basis it shouldn't be much of an issue.
