For those of you who are wanting a GHL muffler and want to know what it sounds like. Here is a video of me driving around. Also I recently install Fabspeeds cat bypass pipes and allot of the drone has gone away. Now it sounds more like a cup car. Its not quite but it sounds mean. Let me know what you think.
