My cousin has a 02' WRX, would give me like 20 cars on the highway and would still blast past me. All he had was fenderwall CAI and a Nurspec (spelling) catback. Those cars are strong. I know my tour is old and might not be up to par, but it's hard to keep up with a WRX even if you are lightly modded. I am going to check out the sig right now though that does sound funky, even with 240 hp wow I didnt know you lose that much to AWD.
