You're losing some low end torque by running the dumps instead of a true 2.5" tailpipe. I ran turn downs (dump offs) on my car with 2-chamber Flows when I first rebuilt my motor. A year or so later I put tailpipes on because it was so loud I was sick of it...I picked up a ton of torque down low...and gained a little in the quarter just from reinstalling the tailpipes.
