yes it has a deep sound, i set off car alarms too if i take off to fast down my street. ill try to take a video of my truck running and post it, so you can hear what it sounds like. i really like the way it sounds, especially when i take off real fast. i got the glass pack at jegs.com for $45 dollars, plus $10 bucks for handling. i think the shipping was free. the muffler shop charged me $35 bucks to cut out the stock muffler and weld in the glass pack.
