this is going off whats his names question about the race header producing more sound. i have a magnaflow and k&n short ram and its not loud enough but in pa i think they are going to be passing a cat law. so puttnig in a ford racing header and high flow cat with new flex pipe would open it up and put an authoritative tone on my car or no? it is hard who has these things?

if u upgraded just header u get more noise?

if u upgraded just hi flow cat u get more noise?

if u upgraded both u get more noise, but how much?

if u upgraded just flexpipe u get more noise? does it help it much?
