I recently picked up a stillen gen. 3 intake and am looking at what's the next best route. From what I've seen berk hfc, stillen catback, f.i. catback all make around the same gains individually. Semtex made well over 30 at the wheels with hfc/catback combo but others are seeing minimal additional gains when adding hfcs to a catback. (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.
