I've had mine on for over 2 years now, it hasn't had any issues so far. I love the way it looks and the noise it makes when I punch it. Make sure you buy an extra filter, it makes cleaning a lot easier.
No whistle from mine. But I'm used to my ford diesel, that had a sweet whistle to it
Mine came on the truck so Have a question...Someone above mentioned they make a dry filter. So I'm assuming they have both? Any way to tell what mine is besides just pulling it and looking for oil?
