when the turbos were replaced- no cats, no res, only a muffler-still emissions legal in pa
02 sensor is stock- I have a wideband 02 that I was going to put in when I bought bigger turbos this summer but since I am selling the car I already sold it as well as the gauge and software to a local guy
help me sell this so I can buy m3 and hpf stage 2.5 this winter if I work enough hours and my scholarship comes through
