Does anyone have one of these? I was wondering how much louder they are than stock and what kind of sound they make. Any feed back would be great.

I have one
 

I like it, it gives the car a very nice low roar. It is kind of droany though cruising at highway speeds, but I still don't mind it. If you're looking for something with a really nice sound and don't mind a little extra volume, I recommend it.

its not really loud.the drone isn't really noticeable especially with the radio on. an intake is much louder

also might want to consider
