damn, i was lucky when i had my 08 with a tsudo catback, i never got pulled over. i just picked up a used 07 wrx sedan and it was an apexi world sport (just axle back portion) on it and it is very subtle, but still produces the rumble.
i was thinking of buying the SRS but am not too sure yet, especially if i end up getting a DP in the future. im thinking of having my friend fab me a 3" midpipe though, that might give me a little more sound.
to the OP, id hate to be in your shoes right now, im not sure what i'd do.
