Sorry for reviving old thread..Just for future reference:
Why don't you use canbus ? Muchh easier and painfree.
I'm actually working on having my exhaust valve open up when the sport mode is activated on my AT. (those catback with varex valve) with combination of arduino, canbus shield and rf transmitter (or relay). It's plugged right into the canbus data 6 pin plug behind the stereo
