okay, i come to understand these products as so from reading on here and honda-tech.

APEX'i World Sport 2 - looks great, low sound, not a lot of HP gain.
Invidia - REALLY loud
Greddy Evo - REALLY loud, decent HP gains

how does everyone feel about the DC-Sports line of cat back exhausts? and does anyone have anything to correct or add on what i said about the other three above cat backs? i'm having a hell of a hard time deciding. my main goal is for the I/H/E to gain 20-35HP without sounding a coffee can. is the DC-Sports line of cat back exhausts any good?
