Just got the MagnaFlow cat-back exhaust system (15072) installed on my 2012 hatch. The tone is gorgeous and the car pulls beautifully now, but I was expecting it to be a little louder. From what I've read, there is a break in period of a couple thousand miles with these things, but the noise will only increase slightly. Some say to delete the middle resonator and that should increase the volume a bit more. Is this a good route to take? How much will this affect volume and/or horsepower?
