cat less

All information above is correct. I'm a state inspector and we are suppose to check for cats during our inspection. Given there are plently of shops that do not do their job and check for them. As long as no check engine light is on I'd sy your nearly 80% in the will pass and maybe 20% that an actual inspector would check and fail you.

From many years of car modding and inspection experience, this is correct. There are also certain times that you can go in where they are less apt to check under the car than others (specifically when the managers aren't standing over them because they are busy).

This is why I am considering getting the high-flow catted X-pipe for my car when I do headers. There shouldn't be THAT much of a loss compared to catless, and no inspection worries.

I ran an offroad h pipe setup on my 2010. I did the oldschool non-fouler setup but slightly modded in order to get the sensor properly positioned with just enough exhaust flowing over it so that the computer still read as if there were cats. Worked great and passed inspection no problem.
