I got the B2 Fab Magna Flow in yesterday. I am very happy with my decision because I wanted my Hemi to have a little growl without being overbearing. I was hesitating to do anything because I pull a 31 foot travel trailer in the summer and didn't want annoying drone or cabin resonance when pulling and using higher RPM's. The B2 Fab Magna Flow is perfect for those that want a less extreme exhaust note.
