Wanted post my observation regarding the "golf tee mod".
I watched the exhaust/muffler flap valve one morning and noticed that as soon as the cold/fast idle drops the valve opens automatically and says open my car and exhaust tone remains constant at low RPMs and has a deep tone.
Could the ECU programing be different for different model years?
Typo?
