Hello, the new Daynas create the required values of the ASU also with the e.g. exhaust system Kess-Tech manually transferable in closed condition ? Or how is this if you have to advance with the original exhaust system u. later converted again to the Kess-Tech . In case the values do not correspond our friend & helper will surely monetize the mounted Kess-Tech with a control or ? How does that work ? Or are the values in spite of another approved system oh a cat so good that they can withstand each ASU exam ? Who knows more precise ? Bernhold
