The sound of this exhaust is sweeetttttt and It's not too loud. When your gassing it then yes it gives gives little roar sound, but when the car stops or yiu take your foot off of the gas it's very quiet. I have a q50 AWD and I could ask for a better exhaust. I picked 2 day shipping and it literally came within 2 days. The exhaust doesn't hang low like how you would see it on other cars, so if you're going over a speed bump you'll be fine.
