Sorry,i know it's not a cool intro but i needed an answer,i'm the 3rd owner of my MY06 Wrx and i still can't get many answers to what has been don to it before i got it,having never owned one before i have loads of questions.It has a high flow cat an a 3"exhaust,not sure what else has been done or how it should go but it seems to be able to spin all 4 wheels in 3rd without much effort.
