So let's say you're driving to the track on the streets to avoid towing. The car usually gets no attention and everything is as hidden as can be to maintain the sleeper status... however, it's still loud and slammed so you KNOW it's modded.
A cop hypothetically pulls you over, while not committing any traffic violations, and says your car has no front plate, is too low, and is pretty loud. Pop the hood.
You know the giant precision turbo, methanol lines, custom shiny intake manifold, and 3" turbo back with only a muffler and turn down before the axle will not go well. You were not accused of or pulled over because you were speeding, driving unsafe, or exhibiting anything specifically done to the car, so you want to say no thanks to the officer making the request.
What happens next...? Pray to Jesus? Just flat out say I appreciate the concern officer, but I would like to respectfully decline as that is not necessary? Or say sure why not, pretend to be dumb and see what he says?
I'm only seeing a greater fluctuation in responses as I suppose was expected.
