I just looked at the stock radio, there are no rca outputs coming off of the back of it and the only sticker on it was the DAEWOO sticker which had the model # and like a diagram of the wires. The word REMOCON was nowhere on that sticker either. As far as I could tell nothing about remote connectors just front speakers, rear speakers, etc.
As for the exhaust, I plan on getting side skirts, when I find a set I like and then I will have a hole cut in the driver's side for the exhaust to come out of.
LARSBUD - it was easier to bring the exhaust out of the drivers side of the car because of the way it is piped underneath the car.Basically it comes from the front of the car and then makes a 90 degree turn towards the drivers side and then another 90 degree turn to go out the back of the car. The underbody and everything has been designed for this meaning there are already indentations and everything to allow the pipe to be closer to the body of the car going towards the drivers side. It will hang pretty low if you re-route it to come out the passenger side because there are no indentations in the body going towards the passenger side, so you'll have to re-route the pipe to go underneath what's already there and that will make your pipe pretty low to the ground. Just a heads up.
