so Mike K. recommended the fmax kit be 2" id piping coming out of the turbo, and 2.5" from intercooler to throttle body. should be good for up to 400hp. anyone else have there opinions on the size piping out of the turbo, 2 1/4, 2 1/2? i'm setting up for a t3/t04e 50 trim, .63 a/r compressor, .50 a/r turbine housing stage 3.

what mike said, I'm sure it would fulfill your every desire...car wise.
