I just bought my G6 about a month ago and want to add some HP to it. I have a 2008 G6 GT, V6 3.5L. I do not know a whole lot about tuning cars or anything like that but I do love them. I just wanted to know what mods I should start with and then which ones after that. Anything with the engine, exhaust, etc. Any help would be greatly appreciated. Thanks!
