I got an 06 3lt impala and am thinkin about adding an exhaust system. I was just wondering if i should get a custom one made and also what would be a good size for the piping?? suggestions are great,thanks=)
the stock exh size would be more than enough for a N/A car, plus im sure theres a few areas that you can "free up" the flow a little, ie down pipe etc,
