Personally. I think it depends on the way the car is modified, and the way the driver drives. Because, me personally, i've had my Integra for 2 years and when I first got it, I went ahead and slammed it, ordered a custom tag that took the state 3months to make, and I also went and threw a fartcannon on it. Sure, they sent me a legitimate temporary tag to put in the rear window but still left me VERY vulnerable to constantly getting stopped. I actually stopped counting after the 15th time. Its gotten warnings for loud exhaust, tinted tails, and even being too low once.

Prior to that, i recently went and put a ''real'' muffler on my car which made it MUCH quieter, raised it up a bit, and made it far more conservative looking and sounding; I Haven't been messed with ONCE since then. lol.
