The "standard" '09 touring header is for a 96 ci engine and has the first-generation, larger, O2 sensor bungs mounted up nearer the heads. Yes, it'd be a direct bolt-on replacement and would be the suggested method vs. gutting the cat, if the header in question also has the same bung configuration.
If the header in question has the newer, smaller heated sensors mounted down by the transmission then I'd suggest a an aftermarket replacement header like the Fuelmoto or Fullsac offerings. With the cat removed from that vintage stock header the "collector" is really more of an open chamber and the two sensors will not as reliably sample just their own cylinder's exhaust, assuming the intention is to continue using closed-loop operation. If the ECM's auto-tune-maintenance functionality is going to be effectively thrown away by running totally open-loop then it will work quite well. Wouldn't be my choice to go that route, though.
