(Fast intentions only sees another 5 whp when adding hfcs to their catback) If that's the case then I dont' see the reason to go through the hassle of taking the cats off and possibly dealing with a cel other than having a more aggressive sound. I think a cai, catback and ecu flash is going to net you pretty darn close what others would with headers/hfcs in addition to those mods. I'm just a college student so don't bite my head off about being cheap but if you can get 40 at the wheels without headers and hfcs I think that's a pretty good way to go.
