When I bought my 7 I was told by the guy I got it from that it had the mazdaspeed exhaust system on it. I have no clue as to if this is true or not and I dont need it anymore since im going turbo on the car anyways... So before I sell it to someone I want to know if it really is... Does anyone have this and if so what are some charistics I can look for to make sure it is what it is claimed to be.
