i have a FMIC on my car, (happy to do swap with factory 03 STI setup if someone wants. bumper and all if need be.

i noticed on the 06 WRC car at Rally Oz last year and on the pics we saw in these forums that they reduced the piping right down to 2 or 2 1/2", my immediate thoughts were, "well that must reduce some lag, less volume, cool idea" a bit better than the 3 1/2 or 4" piping you see on most cars.

always an idea !!!

2" pipework is the go.

I got a FMIC. I want my Toppy back...
Instant (and very noticeable) difference in lag and throttle response.
Plus pain in the ass mainenance.
Power isnt everything, its how it drives - not what your printout says.
(I thought this is why most of us drive WRXs and not Commobores anyway?)
PS.They do look cool though. I love the "ooh, intercooler!" stares.
