Still looking for some piping? I got a TurboXS FMIC kit for sale, link below:

I think the piping is 2.5" the way through except for one pipe leading to the throttle. Hot side piping doesnt go down under the motor, but up and over it like most kits, then goes down at the front of the motor.
P.M me if your intertested.
