I like TurboXS.

Comes with a replacement bumper support, will keep factory fogs(of 02's and 03's at least) and is oooh soo purty. Great quality too

IMO, keep your factory TMIC until you upgrade the turbo and engine management is available.

Depends on which APS you are talking about, but here are some numbers on the Turbo XS, Perrin and APS FMIC:

DR 600 - 19,600 cm^3
DR 500 - 13,023 cm^3
Perrin - 20,058 cm^3
TXS - 14,472 cm^3

I hope this helps.

Yea I dont know performance or flow numbers on the TXS.

There was a post on, NASIOC maybe where it was actually a 4lb weight savings over stock!

The APS front mount is collosal. Combine that with the miles of piping required to plumb the thing and you're looking at quite an increase in lag. Are you sure you really need a front mount? Personally I'd stick with the almost lag free top mount design until I had no choice. There are aftermarket top mounts available...
