If you have salt, your flowmasters are good for two winters, maybe 3. The magnaflows on my work truck have been on there for 6+ years with no problems what so ever. They also sound better (IMO) and maybe it's in my head but when I replaced the flowmasters on my f150 with magnaflows it seemed to gain a bit of power down low.
