For my Maryland inspection I stunk out the whole garage with no cats and they passed me because I didn't have a CEL. Top of the line headers from ARH, SW, and Kooks usually run around the 1k-1.2k I believe. It might be more with cats.

That's pretty funny, I forgot that when you don't have cats you can also smell the difference in the exhaust.
I'll have to look into the high flow cat options or test pipes if that will really change the sound. Even if it becomes an issue, they wouldn't be that hard to bolt the stock ones back in.
