Hi, I am Jim. I bought a 2006 G6 SE about 2 weeks ago. It has the terrible Spyder headlights and I have to deal with them for now. I'm going to be putting LED bulbs in the lows. If they aren't any better than I will do a 5000k hid kit. It has a Flowmaster muffler and tip on it. I plan on swapping out the climate controls to 2010 as well as gauge cluster to move the DIC and put in a double din with GPS.
Welcome to the club. I had 5k's in the spyders, you can put spacers behind the bulbs to help out a little. We had a group buy years back, if you can find the thread it explains how we were able to get the most out of them. Good luck!!
