They do but you don't see it publicized that much.
There are 63 national Parks and a couple are split by state or US highways. So technical if you get caught it can be either or and even both criminal and vehicle code violations. As for the rest a felony can be charged on any land you have removed and operated the emission control devices specifically on the exhaust system/
Federal property refers to any property or asset that is owned or controlled by the government of the United States
The most predominate insistences we more frequently read about is when off road bikers remove the spark arrestors on their bikes or OHV's.

The funny thing on forums I can also always tell those that have no real clue about building more power when they start talking about or have done a "perfromance CAT" replacement and stating it was to improve the exhaust flow. Most all CAT from the factory at least from various platforms manufactured from about 200 and most all from 2020 are already a high flow CAT. lol
Most would sheet their pants if they knew what the normal operating temperature of their CAT was.

 

Interesting how I never heard of Ansen wheels. Oh well. My friend with the 1969 Chevelle had to drill holes through the bead of the tire to help keep it from spinning inside of the rim. His car was street legal - albeit hard to drive in traffic - and his 'normal' tires rode on Cragar rims. For track day, I think he used Centerline or SS/T wheels with drag tires. He also attached wheelie bars to keep the damn front tires on the ground. He owned that car until up in the 1990s. I last saw him in 2023 when I went to PA for my high school reunion. ( He was two classes ahead of me and lived a couple blocks away. ) He later turned his affection toward drag bikes.

He is now 63 years old, inherited his childhood home from his parents, and is still in the same town! He can work on cars, aircraft and is also a diesel mechanic. He had some medical issues a few years ago and had to 'scale back' a lot of his hands-on work. He is a parts manager ( or something like that ) for a big truck dealership. If I recall correctly, they sell International. Regarding tires, I am not sure of the exact brand.........but I do remember him having Mickey Thompson literature in his shop. I just cannot believe it was more than forty years ago. Time flies.

Sounds as if you had some very interesting experience with "Frankenstein" cars over the years. I've seen some interesting ones too. One that sticks out was a Ford Pinto station wagon with a Boss 302 stuffed under the hood. Another chap took a 3.8L turbocharged Buick engine from a Grand National and shoehorned it into a 1978 Chevette. Both were the ultimate sleeper, even though they looked pretty odd. I don't think anybody was worried about cats back then, but with modern cars, I am not sure how much different it would really make to run without one. It might be hard to tell by looking at a car if anybody tampered with the emissions control equipment, but when you see a late model diesel F-250, Silverado or Dodge Ram with straight pipes out the back.........then it is obvious that somebody hacksawed off the DPF, DEF, etc., in order to do that.

Before I retired, I couldn't help but notice how most of the reason for our tractors and heavy straight trucks went into the shop had to do with the emissions equipment. Sometimes, they just reflashed the computer, but other times they had to replace the whole EGR/DPF components - which cost thousands of dollars! No wonder there are drivers & small fleet owners out there who love to purchase "glider kits" (a new big rig without an engine) and install a remanufactured Caterpillar, Detroit Diesel or Cummins "pre-emissions" engine. As far as I know, that is perfectly legal as long as the truck never enters California. The Golden State would probably execute you for trying to haul a load there. Haha!!

on ebay. lol



Here you go my actual 12 second wagon with the Ansen Sprints in 1976

 

I can always tell when any car passes me and I smell the exhaust if they would pass or fail not only a visual but tail-pipe emission test.
Up until last year for the last 2 decades I was certified by the State of CA to perform emission testing.
I am not sure I would call some of my past cars "Frankenstein" most were modified to fit the time period with only a few exceptions. I never really got into any trucks, nor did I ever own a Low-rider.

The Buick Grand national was truly POS having owned one. I was always amazed why some choose to use that as a engine swap project for another platform and model. However, I engineered and almost brought to market a manually controlled waste gate controller for them that would half wake up that Turbocharger that really belonged on a TANK . And even with that the Turbo lag was so bad you had to hop that you never raced anyone with a well-built BB and could get over 130 in the 1/4 mile cause that Buick would likely NEVER catch up. LOL If you look my 22 year old Sation wagon carbureted before the Bicks conception ran quicker times. LOL

Center lines and Mickey Thompsons (MT's for short as they were called then) and they were the in popular combination in the early 80's. I had Centerlines on a couple of my Camaro's and mustangs. My favorite for street and trac was 15x3.5 front with a Michelin tire and 15x10 rear on Miceky Thompson N50x15.

 

Very cool.

Love that Oldsmobile wagon. That is a sleeper for sure.

 

That is a newer terminology, you should know back then there were only Trucks, Low-Riders, Gearheads or Hot Roders. My station Wagon was known in 4 cities. And I was banned from parking it in the Highschool student parking. lol

Now a sleeper would have been my bright RED 2009 PT Cruiser. I sold it last year. Think about that Chrysler put a performance Turbocharged engine it factory with no detuning? After a few of my personal touches and debagging completely . It would haze(spin the tires phantom grip) in first and still do 5 second 0-60 and a very acceptable 0-100mph time as well. Sorry I never posted what it did on the 1/4. But I will say I often used the bottle at the track and few times on the street.

 

I saw a P/T Cruiser not long ago and almost forgot what it was. It seemed as if they were everywhere and then - Poof! - they just disappeared. If memory serves me correctly, they made them from about 2001 to 2010 or so - but I could be mistaken. Chevy had the HHR, which sort of had that same look to it, but wasn't nearly as stylish.

 

I live in a Del Web retirement community and up until 4 years ago you could not drive anywhere in my city and not see at least 2-3 different PT Cruisers. But now the trend is SUVs or Tesla and the predominate color is silver or white. So now people I know wonder why I no long wave at them? They all look the same to me? LOL

 

Very cool. That was what you call redline shifting.

What engine, a 2.2L inline four-cylinder?

 

I made the video in standard auto shift (not manually shifting) and let the ECU decide the shift which it short shifted as i suspected it would. The engine is a Chrysler 2.4.
