Depending on which pod you get, some are louder than others. I have an Apex one, and it whooshes like no 2morrow. If you boost, it will attract attention, and I dont like that.
The panel will be the best choice if you dont want the sound, and less attention. THe pod is legal if it is mounted to the car, so it cant wobble around, but a commong mistake cops do is, they pull you over for thinking you have a BOV but really you only have a POD.
This has happened to me, they checked the BOV and came to the conclusion that this BOV just must be louder than normal etc.
If the POD wasnt there in the first place, wouldnt have had the trouble. But then again, I shouldnt have boosted right near them, but how am I gonna pick up speed to maintain the speed of the traffic behind me?
Those are just my thoughts, yes the induction noise is tuff, but I wish the pod didnt have to go pssst after you let go of the throttle.
