I'm down for a Texas chapter but this state is too big to have regular meets. As for modded P5s i know of three in my area, a silver one has an Msp front bumper and is lowered with rims, another blue one has a catback and rims and a black one has a catback and rims. Every single other P5 is stock, and they are popular around here, I see a handfull every day.
It's not hard if you divide it up into North, South, and Central Texas cheaper.
