The exhaust setup is basically the same (not identical) as it's ever been on the Evora as well. Two primary cats on each bank, collects down to a third cat, with a valved exhaust that pipes through a direct pathway in the muffler in sport and track modes.
From an emissions point of view the third cat was still needed to pass emissions for the Evora as well even at a federal level.
From a sound point of view your state (TX) also has vehicle codes regarding sound and likely local municipalities have sound ordinances even stricter than the state or federal level.
As context what
@Hell4Leather is bent up about is the drama that unfolded with the Veloster N case in California where a police officer cited a Veloster N using specific drive modes that aren't really meant for public road use. This has _always_ been a grey area and always will be. My M4 with an OEM M Performance exhaust makes lots of pops and blows sound @ 103dB -- it's still "legal" because it isn't a default driving mode. It basically just comes down to enforcement.
Texas is an even bigger complication because they have a very vague law about exhaust sound. If any cop deems it be "excessive or unusual" it's in the wrong -- there isn't even a db limit attached to it.
