Damn, that is really some nazi crap they force on their own people :-(
No wonder you're all not into high performance, doing mods or custom tunes, you're brainwashed by those commies holding office that a good vehicle has less than 150 HP and never going over 55 MPH,
that is boring, so I think all you hardcore Corvette owners here should move to the USA just to be able to haul ass and doing performance mods
As I mentioned here in the USA most counties do not require any safety inspections, most do not even require SMOG testing anymore
as been proven that American vehicles made in the last 20 years were designed for clean exhaust output
Even with all the mods on my 1999 C5, engine stroked, larger fuel injectors, custom CAM, etc and Cats ripped out with headers
passes the on-board smog tests and zero error codes trip, but of course I custom tuned the GM calibration in PCM to make it 500 HP,
30 MPG on highways and outputs clean exhaust
Some counties only require a SMOG test that all a shop does in plug in a OBD-II scanner and if the on-board smog tests are in a complete
state and the check engine light is not on, then vehicle passes
