I'll probably get flamed for this, but cops notice 'tuners' and the majority of them are Honda Civics anyway.
Doing mods on a car is fine if you plan on going racing on a sanctioned track, but these assholes that mod up their cars with airplane wings on the rear deck, big ass fart can mufflers, neon blue lights everywhere, N-O2 tanks in the back and then go street racing, they deserve all the grief the cops give them.
