Just added the magnaflow 18" on my truck and its just perfect for me.Not too loud, but you can still hear me coming. Very happy with it. I added the Line X bedliner 2 days ago and im PAITIENTLY(the wait is killing me ha) waiting for my Vararam Air Grabber to arrive also my dball remote starter.
MODS: MAGNAFLOW 18", LINE X, DBALL EXPRESSKIT RS, Diablosport T1000, VARARAM AIR GRABBER.
18 with resonators is kinda loud but no where near annoying. The drone is only at about 45 mph with the ECO on. switch it to 5th gear in town, problem solved. The drone is so minimal though, it's almost inaudible in the cab with windows up. You feel a slight vibe more than anything. I'm 37 and my Dad's pushing 60 and he thought my 18" MaxFlow was perfect. Mine got a few db's louder after 3 months or so. Sounds amazing when you rev it out in 2nd or 3rd.
