So far I have de-cat up pipe, Big Jays old exaust, which consisted of 3inch hks decat centre and powerflow 5inch jap style back box, but want to let all the cats out the bag (Did you see what I did there, CATs get it?) any recomendations for decat down pipes, looked at Japspeed and H&S so far but wanted another opinion
Many Thanks
