Exactly, I have buddies that are state troopers and I'll guarantee not a one of them would even know where to start looking for a converter, and even IF they did, my car sets 2 inches off the ground...do you think that a cop is going to get down flat on the groung in his newly-pressed uniform on a hot, dirty interstate, with traffic whizzing by at 70 mph, and pull out his telescoping collapsable pocket mirror and flashlight, fumbling around hot exhaust pipes trying to see under a low-ass car just because he "suspects" that you don't have cats? Not a freakin' chance!
If there is a cop in the country that would do that it would be worth the price of the fine for me to stand there and laugh at him.
Not even Barney Fife is that zealous, screw em', stick the off-roads on and when you have an inspection (if you are infortunate enough to live in a state that requires it), throw the stockers back on....it takes 30 min.!
