It's all about selling non-compliant emmisions stuff, and things like tuning stuff that makes your car have more emmisions, a very small percentage of modifications and tuning go into race cars, the vast majority of tuning and mods, like catless exhausts, or non-compliant cats, go into street cars with registration
Like a gun shop can only sell to someone with a gun licence, if they don't, they are fined and even jailed, and whilst a gun is totally different to a tune, or a catless exhaust, they are still illegal for a street car
As for customers, it easy, they send a letter and tell them to show up for an inspection, like if someone says your car is to loud now, if they don't show up for the test, they can cancel rego, just like not paying a traffic fine
This has been happening for years overseas in other countries
I'm in no way happy about it, but, I think there is definitely writing on the wall for modern cars with emissions standards, which will effect tuning shops, parts suppliers and end users
And like other countries around the world, it is the government's that makes the rules and regulations for street cars with rego
What would happen to a tuner or workshop if they were investigated about turning off stuff in a ECU IRT emmisions stuff like engine check lights for cats, or removing cats, or putting in a lower cell cat, this is apparently all illegal IAW modifications to registered cars, or, retuning the car so that with even stock emmision stuff still installed, but due to the tuning, or parts, like bigger cam shafts, it will now not pass the emmisions test
Yes, I am going into a rabbit hole, but going off what other countries are doing IRT everything related to emmisions........cars, trucks, manufacturing, mining, modified vehicles are a easy target
Meh, time will tell how it goes either way
