i would go stainless personally. i have some shorties on my truck and they are wearing nicely. the only problem i ran into with them was that the flanges where you bolt up the pipes were 4 bolt instead of the traditional triangular design that has three bolts. i fabricated some plates that have 4 holes drilled in them and gave them to my muffler guy so that he could weld them onto the pipes beforehand. No problems so far.
