Ahhh, so did you actually try all those exhausts on the same car in one dyno session?? Both SCA and Borla shown to gain more power than you are showing on an SVT...Your endorsement for the CarDoc system is impressive, almost "advertisement" like. And the first numbers are from an ATX SE??? Pretty good numbers.... But, you like it and thats what counts.
