Mine sure does, especially in parkades

The other day I got asked not to park in one of the parkades at UBC (University of British Columbia) because I must've set off the alarms on a dozen "sport-compacts", It was funny listening to all of them echo and see all the lights flashing

My car is parked beside an integra at my building and if it's the first time my car's been started that day it's alarm goes off and there isn't even much for the sound to echo off of. Anyone else's car seem to do this? Maybe its the X-pipe combined with the MAC mufflers.
