So I have my 12 SWP 4dr on order still. I wanted to buy the SPT exhaust just for the sound because I don't want to mod it until my warranty is expired. When I go to my dealers website (from the SPT website) it only gives me an option for impreza or STI 4dr. Do I select the STI or Impreza??? Probably a noob question, I know. Here's a screen shot of what I see.
