I chopped mine out before xmas. It's not THAT loud, but it is noticeably louder than the stock exhaust. The only time the car set off car alarms is when I started it up with nothing from the cat back and revved the hell out of it. 2 problems, When it's cold..it's a little raspy, and, it always sounds tinny under hard acceleration. for me it's an interim thing until I can get a real exhaust on there.
