I'd be willing to bet my car is louder than yours...even with you blocking the ports.

My point here, is sooner or later you'll be on a non-frisbee sized pulley with quite a few mods wondering.... "Why is my car this loud?"

Downshifting, I've been mistaken for a police siren.
Can't press the pedal w/o gaining the attention of everyone w/in a 100 foot radius on the higway.
And my personal favorite..I got a ticket for left on a yellow after the cop heard the charger. Probably thought it was tires.
