Hey guys I've had my car with a racing beat header, FM midpipe, and roastersport3 exhaust for maybe 3 months now. I had it for a year without the header but that made it too loud in my opinion with the top up and for a dd. I know the racing beat, magnaflow, and cobalt axle backs are supposed to be quieter but it's impossible to tell from videos which of the three is the quietest. If anyone has experience with these in person that would be helpful. From what I have gathered though the cobalt is the quietest other than oem.
