Hello Audi fans, my exhaust pipe between Krümmer and Kat had a small hole, I thought so, well, drive still fast to the vocational school and then straight to Stettin to the exhaust factory and get you a new one……. well, after the school I first go home and then direction pole (about 30 km)……. about 10 km before Poland it happened then….. I drive so between 80 and 90 and then ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄMM!!!!……… I thought I was driving tanks that was so indescribably loud….. the poles build the anyway not at so drive again direction home…. in every village when they were standing at the fence or so I made gas :-)) what do you mean like the looked they have shrugged together :-)))) I think I pulled with a broken exhaust more eyes on me than a healer ferrari would have done then ordered a pipe… (100 € with seals, bolts etc………..by BOSAL) so and now to ask, I ordered a valve lid seal with it. because my is as good as through………. I have to pay attention to something when changing??? the camshaft wheel can stay on or?? MfG Julius
