don't know what the emissions standards are in CO, but I would think just about any header should work for you. a lot of the companies have y pipes available nowadays
The emission standards are pretty rough here in Denver, the rest of Colorado is pretty lax.

I just want to make sure there are bungs for the O2 sensor and that there is good clearence with the headers.
