Hello to each other, I bought last year an Import Mustang GT 2010 4.7 V8 Premium from a local dealer. I now have the following problem with the weighing machine, I don’t know about this yet but I have TÜV in July of this year…. According to a DB measurement, the good piece was 110-118 DB with false ignitions, according to the vehicle license, of course, he can only have 75 DB, during the last inspection in September I have looked more thoroughly but no middle class allmämpfer found, so I assume that the mustang had none at the time. At least I didn’t see any on ebay with all the original systems, only the bells under the H after the cats. The rear silencers are at least the same optically as the original ones, both have their Ford badge on it, so I assume that the ESD has been cleared empty, with the AU that my buddy made spontaneously yesterday nothing came out that on an empty n KAT or something, if you could see it at all, as I said there is no expert knowledge. What should be mentioned, strangely enough, the colder the engine / exhaust is the louder it buzzes of itself, if I leave it completely cold it really bubbles. I would of course let the AU make with a buddy the certified and with the to our GTÜ which presses the eyes anyway, even with middle silencers which are actually only empty pipes however would mic h it ́s really interesting how this sound comes about now, if an import car gets muffler installed you can make it out by any characteristics? Zsb. at a glance into the tailpipes. I would like to fix the problem if the examiner waved off, and would like to be on the road with the conscience that my sweetheart will not be directly shut down and towed, even if it seems to care with us in upper Swabia no police officer It’s a car.
