i current have true duel flowmaster 40 series on my 01 v6 stang with the stock y pipe, stock converters and headers, the piping is 2.25" . I am not that pleased with the sound. Does anyone know if i went to the gt H pipe set up would the sound deepen at all (close to that of the gt)? is flowmaster better than mac exhuast? also if i got the H pipe set up and went with 2.50" piping would that increase sound any? would i have back pressure problems becasue someone told me back pressure is a myth and thats why im considering going with larger pipes
