What kind of Emission laws do you have? Here we have to have our cars E-Tested every 2 years. Do all those mods have any trouble with that are?

In Washington State it varies from city to city and county. As you get closer to a city, you are required to pass emissions prior to renewing your tabs. If you live out in the country, they leave you alone.

No emission testing in MN. TX has E-testing in the metor areas, DFW, Houston, Austin, etc..,If your car is registered there. To get around that have a p.o. box outside of the county and have your car registered to it

I'm tested every other year. Just did my testing in March. And I passed. That'* with all my mods and no EGR. I left the cat but have a free flow. My car is very far from stock.

No E-check here. There'* only a handful of counties left in Ohio that still do it.

Palm Bch county now has none for about 10 yrs or so.Out of 67 counties they only grabbed a handful.Such as Dade,Broward & Palm Bch.

None here either, only Albuquerque, and El Paso, TX to our south.

im not sure about it here but i never did in the 6 years ive been here

only when you bring a car from out of the country or the province

Thats good to know that after some serious mods still no trouble to keep it on yhje road legally

There'* no testing or checking here in Indiana. There are maybe two counties, but otherwise we're good to go.
