They both taper down to 2.5 inches right before the Dp/mid-pipe connection, so its really not gonna make much of a difference. The best thing would be to go with a full 3 inch system and then 3.5" for the solo piping like AR downpipes with the horsepower freaks exhaust system if you're looking for the true highest performance system. That's the only setup that's really gonna have an advantage over any other. And really its only necessary if you're at like 450 whp+
I would just look at which one is built better or made fully out of T304 (including the flanges) and then buy that one.
