As for the power or torque loss, you are imagining it. An axleback alone will not have a noticeable effect on power detectable via but dyno.

I have had ten different exhaust setups in 14 months and I want to try the Eisenmann Race but I can't stand the ugly canisters.

The connecting pipes will make no difference. The only difference between the OEM ones and Eisenmann as far as sound and performance are concerned is that the Eisenmann ones are shiny.
Yeah maybe my butt dyno needs some calibration , or I might be going more easily on the throttle since the exhaust is so much louder or something like that.

I like the black series canister, it's pretty much invisible. A bit more pricey though.

The connecting pipes are really nice compared to the stock ones which are flattened at some points. They'll improve the flow for sure but whether that would be an audible or performance difference is another question.
