I was watching true life i'm a street racer and they showd somebodies cold air intake and the cop said that it was illegally modified. How is this so and how can i do it?Or is there any other way to make my cold air sound louder?

a smaller diameter pipe should be louder but will decrease performance.

and as for illegaly modified, it was probably in an emition controlled state where such a modification (i would assume) is illegal
