Hello everyone, my me is Kaleb and I've just bought my 08 G6 V6 about a week and a half ago. I've already taken off the rear muffler and replaced it with pipe, plus added an intake. I had to do something to add a little noise to it because I just came from a straight piped 7.3l turbo diesel to a quiet car.. but I've already looked around the forums and I'm excited to add more things to the car. Next up is an aftermaret tune to fix the 40mph fluttering during slow acceleration and tint. Any suggestions are always welcome!
