The VX exhaust is around 1/3 smaller then the DX, because the DX engine tends to run that much faster with the torque at higher RPM as well.
On my first VX I ruined an o2 sensor in less then a year by having a slightly over sized exhaust and it's something that I noticed on my current VX along with my brothers VX is that a large or open exhaust seems to lead to lean burn not working right and a shorter o2 sensor life.
