Exhaust - This was just an Idea we wanted to try on so many builds but seemed to get left out, so when GM asked use to do the Aveo the back 2 door looked like a great place to start. The fuel cell also was something that we did and got in the way of the exhaust we did first. Other then that is was really so people had something to talk about when they seen it.
Dash - These are the AIM dash set ups that are seen on bikes and shifter karts which have all sorts of extras for the driver. Lap Time / RPM / MPH / Shift Light etc
