Do they? I haven't been paying attention *that* closely lately, but I usually only see that disclaimer on cat-replacement pipes and such things, not on catbacks.
This appears to be the relevant section of California law (citing CA as it's in my mind the worst-case scenario)
Quote:
27156. (a) No person shall operate or leave standing upon any
highway any motor vehicle which is a gross polluter, as defined in
Section 39032.5 of the Health and Safety Code.
(b) No person shall operate or leave standing upon any highway any
motor vehicle which is required to be equipped with a motor vehicle
pollution control device under Part 5 (commencing with Section 43000)
of Division 26 of the Health and Safety Code or any other certified
motor vehicle pollution control device required by any other state
law or any rule or regulation adopted pursuant to that law, or
required to be equipped with a motor vehicle pollution control device
pursuant to the National Emission Standards Act (42 U.S.C. Secs.
1857f-1 to 1857f-7, inclusive) and the standards and regulations
adopted pursuant to that federal act, unless the motor vehicle is
equipped with the required motor vehicle pollution control device
which is correctly installed and in operating condition. No person
shall disconnect, modify, or alter any such required device.

I guess the million-dollar question would be whether the flap (or muffler, for that matter) is a "pollution control device" or just aesthetic.
I just looked up the Illinois law and it appears to be in flux; they have stopped sending out test notices for pre-1996 vehicles. I guess that means they're getting rid of the rolling-sniff-test stations and just going with electronic diagnostics. I wonder if that means they're going to add inspections like CA has...
