                  I have a Supersprint on mine ,There are straight pipes in its place right now. The tone/loudness barely changed you can hardly tell it's gone. About to weeks ago I went over a speed bump a little too fast and scraped across it which caused an exhaust leak so around 4kish rpms it's real loud and raspy
