I haven't had any trouble yet, no codes or hesitation. I also haven't had the nerve to really punch the gas pedal, don't want to wake up all the babies in the neighborhood!
Thanks again Tone. I had the PV installed yesterday, the day UPS dropped it off. The Axiom has a 2" or 2.25" system so I went with an aluminized cat back for a $150 that matched the PV. Watched the welder the whole time, when they started it up it was music to my ears! I'm kind of embarrassed at the stop lights and take off slowly so as not to draw attention to myself.
