wtfd6,
Considering you have already had two failures of the stock system on a fairly new truck I wouldn't consider anything but stainless and at a minimum T-409 stainless. T-304 will last you forever but costs more. You live in Toledo and you get some pretty tough winters, 409 will do a good job abd should last you 5-10 years depending on the miles you drive per year, 304 will last longer than you and I will, much less the truck. If you want a neat upgrade and since you have a 4x4 look at getting duals. Really looks sharp, and smoking out both sides really surprises a lot of folks at stoplights.
