As for the butt dyno, it was the low-end and mid-range that I couldn't feel as much. Top end I definitely felt, but was afraid that it was the placebo effect taking hold LOL. Didn't want to run around claiming gains if it hadn't been put down on paper yet =P

First, thanks for being able to follow through with the pre- and post-tune dynos - not too many people can do that and often if they do, they have made substantial changes besides just the tune and it's hard to compare. So this is really quite nice. And I tend to agree with you about the mufflers. Realistically, the SS Race cans are straight through, aren't they? If so, I can't imagine that it would make much difference either. So there is another 1-2 feet of straight through pipe with them on vs off, has to be negligible.....
