Anyone hear this..........
I have the slp lid and k & n filter and now I notice when I turn my car off as I am getting out it sounds like the intake is making a hissing sound, almost like it's BREATHING!!!! Is this just my car actually "breathing"? And is this a good thing?
2000 Arctic White trans am, ws6 hood, ws6 air box, slp lid, slp smooth bellows, slp loudmouth exhaust,shift kit, rebuilt trans, LS6 intake, 3.73 gears, Shaner S3 p/p throttle body, and a tune . SFC. C6 ZO6 rims 18" in back 17" in front. Drilled and slotted rotors.

Yes, you can hear the air being sucked through the intake. That is one of the things I loved about my 97 SS! It was loud!

ya know something, I just bought a 2000 trans am, traded in a 2000 corvette for the car, and it has a slp lid with a k&n filter, and it makes the same noise.

yeah, you can also hear it when coasting at city speeds in a lower gear. makes that sucking sound when going through a certain rpm range.

I would guess you're hearing your HVAC system (e.g. A/C depressurizing)...

As stated it's either the AC system equalizing pressures or the electric AIR pump winding down. The key here is the noise occurs after shut down. Unless he is jumping out of the car at superman like speed he won't hear the engine air intake still sucking air. The AIR pump is now heard much louder than before because of the lack of noise silencing that the stock set-up was mandated by Federal noise regulations to have. The A/C noise is normal in most any car as the high pressure side bleeds down into the low pressure side.
