Cold Air Intake surprise sound

[Bulldog2017]

I have a 2017 Silverado 1500, 6.2.  I recently installed the S and B filters cold air intake. First off, I was extremely impressed by the quality of this kit, the ease of installation, and the fitment. I highly recommend it!  After taking off the stock airbox and filter, it is clear that it was built in large part for noise reduction. This leads me to my question.  When driving around under normal conditions, I hear a slightly deeper engine tone and growl, Which is great, that’s the reason I bought it.  
 

However, when the truck is under heavy throttle and acceleration, especially when towing, I would say “growl” is an understatement. It’s not deafening, but it’s more than noticeable. To be honest, I thought there may be an issue with the engine based on how much different it sounded.  I kinda like it, although the wife hasn’t heard it yet and she may disagree. I guess my question is, has anyone had a similar experience with their CAI and I just wanted to make sure this is normal and there really isn’t an issue I don’t know about. I don’t notice any performance drops or lights coming on, so I tend to think it is just the air intake. Thank you!

That’s the point. The stock box is a cold air box from the factory sealed for noise reduction. You opened it up. It’s debatable these days on power gains. Up until my retirement that, exhaust and a tune was my minimum. The butt and ear would convince the brain hey Ricky Bobby were moving.

OK, cool! I knew it would increase the sound, I guess I was just surprised on how much sound it increased by! Like I said, I do like it, I just wanted to make sure that was normal.

100% normal, same on the 5.3L. Love mine aswell. Was a bit expensive but worth it imo.

I'd much rather have $350.00 in fuel.

Up until I retired I didn’t pay for fuel. Everything had a premium tune except my 14. I just put in E-85 for the bump in HP.

for $300 you can get a real 20hp just by throwing a couple switches in the software on HP tuners

"Real" HP? $300, or not it's definitely an increase and it sounds badass.

I was shocked at the increase in sound,  I was not expecting that.  I am fine with whatever marginal gains it gives or not, but glad to hear it’s not my engine having issues!
