Wow, you customized your mufflers?? That's awesome!! No wonder it sounds so good. And that vid of the air bags going off on that ZL1, that car was a gutted out interior and caged camaro for racing and he was going well over the legal speed limit, plus he had the NOWEEDS on there and not the QTP's. The NOWEEDS have the exit of the pipes directly over where the sensors are but the QTP's are more towards the center of the car and away from the sensors. I have had my Camaro up over 100mph with them open, and have had her tached up to 7400 many times with them open and so far no problems. Plus my friend on the forum, Chris runs his Camaro with open headers all the time at the track with no issues.
