moin men. greetings also to you sk8flex. please forgive my rare appearance in the forum. to my question: I have the tss-airintake in it and am very satisfied with the sound resulting from it. however, I think and so sk8flex also told me at the meeting on the a6 that the performance is more negatev than postiev influenced. so if you could please make me concrete suggestions what really brings more performance or at least the serial data can be done. the pleasant sound of the open system should at best not be lost. oh and please only suggestions that also the tüv absegnet. one more question: the new complete system of supersprint?! is it soundly good or rather well. and means the diameter of 60mm really more ps? many thanks already. hope one sees itself at various times.
