Does hypermax make a 3in down pipe and exhuast housing. I don't know the no. of my old turbo but I want to get the egts down. I thought about fabing up a down pipe from my pile of take off factory mufflers and tail pipes. Doing that I would still only have a 2 1/2 in hole in the turbo would that help my egts or would I need the 3 in housing?
