I'm going to be running a twin GT35 turbo setup. I'm running the stock 2.75" exhaust y"d to the turbos (t3) housing. My question is should run a 2.5" or a 2 1/4 cold side pipe back to the front? or would it even matter? they will be y'd back to one pipe. I haven't found any real great info on this.

Conventional wisdom always says go bigger, but it really isn't going to matter - so whatever fits best. I would select it based on what fits best and what arrangement you can get a nicest "Y" for when they join.
