i'm running a cobb catted DP on my 12 WRX Wagon w/ stock cat-back. it sounds stock.
eventually i'll get either the SPT or Greddy SP Elite CBE to get a little bit more rumble.
i made the same mistake with the Invidia Q300. LOL. got a ******* ticket with it, took it off two days later. ROFL. i feel your pain.
i have the Cobb SF intake + Box and Cobb Catted DP w/ a Protune from Kaizen. i'm happy with it performance wise... 249HP and 288ft pounds to the wheels... i just want a little bit more rumble.. not noise.
