another exhaust question

I would test on the dyno. The butt-o-meter is not very reliable, sound makes some people feel like something is faster or slower. The least amount of power I have been able to feel is around 25 and it was not easy to tell a diff. I highly doubt you lost that much. jmo

i went 5" downpipe back and felt like it was a little different too, but the loud ass sound it now has makes up for it ten fold
I might be completely out in left field on this this, but I tend to think the butt-o-meter needs calibrated. I'd think that the turbo drive pressure drop is much more significant than the pressure drop offered by the muffler.
I think the turbo really boogers up any effect scavenging might have on the these engines and the effect off exhaust pulse tuning is pretty minor.

I doubt there is any power loss that couldn't be attributed to tuning changes.
Like when you put long tube headers on a car, if you don't retune for them, you'll lose power. But once you tune for them, you gain power.
There is nothing about a turbocharged engine that likes backpressure. The turbine is less efficient with backpressure, and the drive pressure at any given boost level is higher.
