Your car is always pumping out fumes. Obviously, you're sucking in more air when you accelerate (raise rpms). The more air you suck in the more exhaust you are going to put out. These machines "suck" the air into them like a vacuum.

Once again, I'd be surprised if you coasted through one of these sniffers at 30mph at 1000rpms and got a ticket (stock motor ofcourse). After a cam, you're asking for it.

Keep in mind all counties that border Harris county follow Harris county regulations .

I was with a buddy of mine in Houston a few months back in his 94 Z28 running LTs, no cat and SLP Loudmouth catback. We saw one of those machines on an onramp late one night when heading home, he just built up speed and shut the car off and we rolled past it. Once we got away from it, he dropped the clutch and went along like nothing happened, lol. It's been a few months now and no ticket has been sent to him yet, so I guess it works....

 

I dread the day that OK starts testing again. I can't imagine how I would ever get mine to pass. Probably with a case of beer, lol.

I have heard of people with stock exhaust/engines getting tickets from those darn things.

What happens if you are not a local and pass through one, I am assuming you can still get the ticket even though you are not required to be inspected.

 

I live off 290 and Beltway 8. I have seen that truck quit a few times. I have even heard one guy got pulled over by the "Black Knight" DPS officer that runs around 290 and 1960. He said when he got pulled over this white u-haul type truck pulled up and was there for a minute or two and left. DPS officer wrote him a ticket and told him not to ring a pic of his cats on, cause it would not hold up in court.
I personally have never ran through on of the on ramps with this truck there. I run FLP LT's, no cats (their in the garage), FLP Y pipe, Borla Catback.
