Anybody have a 2-1/4" catback/test pipe combo dyno?

I've been searching around but nobody seems to have a combination like this. I want to retain a lot of low end torque for the street and was looking at the Trubendz catback pipes. I'm thinking about 2-1/4" pipes, two full 6" round magnaflow mufflers, one 24" in the original cat/resonator area and another in the trubendz standard muffler location to keep it very mellow, and no catalytic converter as is standard with the trubendz piping kits. Anyone have a dyno of a test pipe/2.25" catback combo with a cold air kit installed and nothing more? I already have a Fujita cold air intake.
