i just bought the helix ss test pipes and after about 10 miles of driving i get the SES light, i checked and cleared the 02 sensor light and after i drive away it goes right back on...arnt those extensions in those test pipes supposed to work? or do i have to extend it longer, if so how? the non fowler?

I put mine on last night, no CEL yet, drove for maybe two hours. If I do get the CEL, I'll build an O2 simulator..

I have a question, my test pipes' O2 sensor bungs are mounted at a stupid angle where the O2 sensors now hang down low below the car. The original Cats the O2 bungs were pointed somewhat at an upward angle... Are all the Helix's like that?

Also, how do you like the sound of them? I'm not too happy with the sound through the rest of the stock exhaust, but when I open my electric cutout it sounds pretty damn mean...
