I would like to hear from anyone that has installed the SW High Flow Cats (via the header system install), and if you are in an area that tests for pollution in order to renew vehicle licenses, whether the truck has passed or failed the test.
Here in Oregon there are two areas that require the exhaust pollution test in order to renew vehicle licenses: the Portland area, and the Medford area. I'm in one of those areas. I believe the Oregon standard is 220 PPM Hydrocarbons and 1% Carbon Monoxide, tested thru the OBD. Maybe other test areas/regions are the same.
