I need to get my car through smog test soon. Japan's smog test is pretty tough and I have a feeling that with my AWE exhaust (100 cell) it would fail.

Would running the car in valet mode (got it through my UMW flash) helps?

 

100 cell? We only sell 100 cell systems by request and to date I have not sold any.

If your check engine light is not currently on then you will pass an emissions test. Check engine lights come on due to emissions related faults.

Can you tell me more about the exhaust? Why did you think it was 100 cell?

Just trying to help. Thanks!
