VRS is another option to consider. I would get the one that has the best price. they are all good pieces. slp and maganflow make a quality product. I would steer clear of the bassani if your looking for an "x-pipe". basically vrs, magnaflow, slp all make a pretty quality x-pipe. they are all stainless. IF you can save $50 bones on one do it. I don't think anyone is going to have any raw data to support one pipe over the other.
