Hello I am a week proud Caprice Classic owner! Have of course to you competent experts a few important questions 😉 The car ran on a 07 he number, accordingly he has a selfmade exhaust system under (very loud) which is definitely too loud for the tuv! I have to do Tüv because I don’t get the 07s anymore (bj 83) My workshop means to me I should clean up an original system without a cat (because he has a edelbrook carburetor) and would be 3 inches pipes n with a 5,0 l stupid sense?! If 3 inches then ab bender or?????? What does it look like with the red flashers I have in it you get the one with a kulant tuev registered or is there an absolute no go! Because the one tells it he did not iced the other again what now? How do I go now?? Has one with it already experience? I hope someone can help me! Thank you already
