The biggest issue with MBRP is that it completely deletes the valves. Without the valves there is no way to use the setting for a quiet startup. So it is wide open all the time. If you want a loud exhaust that can be set in the mode where it is quiet on startup then you'll need an exhaust that has valves or that sllows you to retain and use the stock valves. Typically tho the cost a bit more money.
