Meine deustch ist also nicht zo gut. 😉 Ich verstehe ihr, aber zum schreiben. :con
Fortunately, you can also understand the English language.
First and foremost, you talk about the Pinasco Deps with 27mm flange, but keep in mind originally it comes with an 28mm.
Malossi does use a 27mm flange though. 😉
There is almost no exact data or results how these exhausts compare to each other with the bigger flange.
I think all of the exhausts listed above will perform well, but a separate test during the upcoming exhaust-test 2012 would be nice.
The best results should be always with a good calculated pipe per setup.
The rest should perform almost the same I think.
PS. Calibrata comes also in 27mm and 28mm versions
