Will a cat back exhuast get rid of that high pitched whisp sound?
Hopefully you guy know what I am talking about when the car is idling. Hard to describe.

I haven't noticed any wisp. Is it very noticeable in your car or pretty quiet?

Had an axle back...never heard a wisp. Only sound at idle was the A/C fan

Maybe it is just how the stock system sounds in general.
