I'm looking into an exhaust system (5” TB) and right now its between MBRP and Magnaflow. I don't want it to be much louder than stock when I'm cruising and no drone. When I do put my foot into it I want to hear turbo whistle. From the sound clips I've heard it sounds like the 4" systems have more turbo whistle than the 5". I've heard about Motoblue and FBD systems, but I would like to hear these systems. If anyone could post some sound clips I would appreciate it and any recommendations would be great as well.
