i can relate .. i live in a small apt complex of about 10 units ...
The 1st week i had my truck .. my landlady asked me if there was something wrong with the tailpipe on my truck..

i just grinned and told her they were glasspacks ...
i fire it up early in the morning ...around 4:30 ...
My neighbors have been really cool and never complained about it waking them up ... maybe there just heavy sleepers ...
personally i think its time to get some real mufflers
