No!
From a legal standpoint no long tube headers is "legal" for on-road use if it removes or moves the factory cat. Tampering with a vehicles emission system is illegal in all 50 states

And there are NO legal (CARB) long or short tube headers available for the C6

Maybe someone should just call a local inspection shop and ask...
(My inspection is due this month so I'll ask when I'm there.)
I do not beleive they look very hard during the inspection as long as there are cats present and you pass the ODBII test.
I nornally get my car inspected at the dealership (Austin) and at least a couple of the service techs there with Corvettes actually have long tubes and NO cats...

It shouldn't be an issue...I had my ride inspected Feb. '08 in Houston with no questions or hassles. I have long tube headers with high flow cats and a Borla 2 tip Stinger exhaust.

I know of few Dallas area vettes with long tubes and no cats that have passed inspection. I am pretty sure Dallas county has adopted the California standards for emissions. However, most of the local inspectors just check the cars computer to see if it has any fault codes. The inspectors / techs have never looked under my car to see if it had cats or not. However, if the car sounds really loud, they might look. Anyhow, you can investigate using O2 simulators to keep from throwing any fault codes. I am installing hi-flow cats (3" thunderbolt metalic) in my X pipe tomorrow. Of course most of you know this, but the cats help to convert carbon monoxide to CO2. Carbon monoxide combines with H20 to make Carbonic Acid (i.e. acid rain). Since I have a little girl, I want to do my part to help maintain the env.

Kind of profiling aren't you ? What makes you think that just because someone works at an inspection station that he or she is a high school drop out ?
