Fitted my dump valve myself. Only a little job I know but feeling proud I could do it. This is a result for me as ive never really been near a car engine before other than checking fluids and oil levels lol. Went for a little drive to my drug (subie parts) dealer who fitted a new fuel pump for me, as the stock one was struggling to keep up with the change in exhaust causing the car to backfire and stall. Had an extended drive home giving it a little welly. And have to say problem solved so far. Also eyed up (reserved) larger spoiler with larger front vent, 17" black alloys ready for next year 😆😆😆.
