2018 camaro SS nosie when accelerating slowly
So my car has only 2500 miles on it, Whenever feet is not on gas pedal the noise sound doesn't occur but when i accelerate at low rpms (1000-1500) in order to speed up slowly to merge in a highway for example, i hear a quiet noise that is very hard to describe something like a lot of air sucking inside a small hole sound from right-bottom side of vehicle (From somewhere near rear right exhaust pipe) i tried capturing it with camera but the noise is minimal it couldn't caught it. however, as soon as i accelerate to high rpms the noise goes away
Edit: I noticed that it doesn't make the noise in first gear when just started accelerating from stop, the problems starts in third gear. My car is NPP functioned Explained better here by arpad_m: Quote:

If it's hard to describe and you can't pinpoint the area or noise then I'm not sure how anyone here will be able to tell you what it is either. If you have a dealer close I would take it there.

It's probably normal. Drive it and if it gets worse, take it in.

Mine has been doing it since day 1 as well.
It's like a very moderate air whooshing sound, similar to a sucking sound coming from an intake. However, it didn't go away after supercharger and different air intake installation, so it must be something else (no, it isn't SC whine either). It might also be the whirring of a medium (4-5") diameter fan, but that explanation doesn't feel exactly right, it's more similar to air movement than any noise made by ball or sleeve bearings. I've decided to live with it for now, it really isn't too bothersome and hasn't gotten worse over time.

One thing I realized with my 2018 2ss Camaro is there are several clicks, whistles, noises, etc., I hear that I never heard on my 2013 2SS. I stopped listening and put the radio on louder. Otherwise, I would drive myself nuts.

Could be the sound tube from the intake piped into the car. Its on the firewall above the gas/brake pedals. I stuffed some foam in mine

The intake on mine has the sound tube deleted, exact same noise is still there, so I doubt that'd be it. Anyway, she is asleep and will probably only get out for more testing/poking in March.

If you can hear it even with SC on, then im assume it was pretty loud when it was stock?

Its your HVAC system, the air flow changes from standing still to moving. Keeps cold air out in the winter and hot air out in the summer. Part of the auto vent system.

Nah, now it's only audible when not in boost and is overcome by the SC and engine completely once the bypass valve flips (just as the topic says, it can only be heard "when accelerating slowly"). It's definitely there and, going by ear, still the same as ever.
