You would be welcome in my neighborhood, there's kids in civics that are probably louder than you could imagine that drive by at dark 30 all the time. Its not so bad since the one guy that had a civic that sounded like it was running straight pipes. Worst part was, he kept selling them and getting another one, at least once a month, and they all sounded all extremely loud, always threw the RPMs up real high on every street, and all sounded like crap.
try and talk to said neighbors. whoever they are. I'm sure with a little reasoning and proof that you aren't compensating for anything (which i'm sure you aren't...) they will stop leaving notecards on your house.
