Anyway Andy is the man and he was right those arent F3 exhausts,i called a friend for a 2nd opinion and when he came over my house to take a look we discovered that the end cands read in fairly fainted letters "Dog Fight for racing use only"
I tried to catch it at the photos but it was really hard this is the best i could do,they're 100% old Dog Fight MC18 pipes though,you can see it clearly under the sun light.
