Weird noise after S&B cold air intake install

So when I let off the go pedal, I get a cross between a cat hissing, and whoosh of air coming from the truck. It lasts for like a second.

I thought maybe I was hearing turbo noise that I couldn't hear before the 4" turbo back exhaust, but then I read it is air coming out of the larger aftermarket intake.

Can anybody confirm that?

It is really loud when shifting into OD/4 under load while pulling my toy hauler.

Sounds similar to this guy's video:

^ like blue said.

The only downside is you may want to floor it and let your foot off the pedal just so you can hear that noise ?
