Exhaust, Intake are common mods. I just got a Morgan Tec intake that I am happy with. I did an exhaust mod a couple of years ago. Tone (Forum authority) distributes Alpine Superchargers which is a desirable options for those who want to commit to it. The mods done to our vx's are pretty rudimentary, with the extreme being Tone's supercharger. Due to the vx's being such limited production mainstream aftermarket mods are not readily available. Brake updates, exhaust, intake, urethane (on sway bars) and more aestetic mods are what most do. Look in the accessories link on the home page and you'll get an idea of what some have done....good luck.
