4500rpm is about when those intakes really provide power and it's just the suction side of the engine you are hearing. Nothing is wrong.
It's doing it again. And I'm fairly certain this "noise" is not normal. I know intakes are loud and have no problem with the sound the intake makes as I let the rpm's up.....I like it. But above 4500 or so it goes from loud to a tinney grinding vibration sound that I feel at the front of the car and it resonates to the cabin.

It's definitely not a "suction" sound at at all. It sounds like something vibrating against something. It's too the point that I don't want to rev the car past 4500 as the sound is that annoying......
I'm come let my buddy ride with me to have someone else hear it....as he has intakes on his cars.

Then I'm going to go back to the shop and have him take a look and see if something was overlooked.
