I wouldn't say it's totally incorrect. It just depends what other mods you have. If you have a 100% stock SR20 and a 3" exhaust on it, then yeah you'll prob lose power. But if you have an intake, cams, pullies, ECU upgrade etc at least a 2.5" exhaust may work. You know those cheap headers are cheap for a reason right? (besides the rusting and coating wearing off in a few weeks) I'd say go with a big header and a 2.5" exhaust, the JWR RR cams, some pullies, cold air intake, and a decent clutch, etc.
