Wow nice car! I have a 2008 G6 GT coupe as well! I added the crabs with the front pipe, and deleted my resonator, it sounded so gnarly! For a spoiler i would recomend the hammerhead! It breaks up the boring back end and looks unreal. Really adds to the cars lines. Although the MPD ram air hood is fully functional, im not sure i like the look of it. Search the AIT hood on google, its cheaper and looks better then the MPD hood imo.
