A couple weeks back, I installed an MBRP axle back. I don't drive the zl1 often, and I almost never start it up early in the morning or late at night. I live in a condo here, so my neighbors are all close. We're at the base of a big hill and open space area.
Last week, at like noon, I opened the garage and fired up the zl1. About a minute later, I get a text from the young married couple across the street. "Hey, random question, but did you just start your car? We're hiking in the hills and heard a very loud noise up here coming from the direction of our neighborhood"

whoops
Literally every 3rd home here has a Tesla or other EV now. There is nothing close to the zl1, other than 1 neighbor's turbo diesel truck (stock, but pretty loud). So far, no one has complained, but I need to be on my best behavior
