    Default Supercharger wine

    I notice a difference with my STS-V when I drive I have mostly the exhaust than anything ...I barely can hear the supercharger like as if I doesn't even have one especially inside the cabin when I get on the gas ,I dunno if it's the exhaust or what but I seen alot of videos on youtube with the STS-V with exhausts and I can still hear their superchargers winning ...can someone tell me what it could be be ?

    If the STS has a big cover on top of the engine like the CTS V2s do, they muffle the supercharger whine. It may be that the cars you're listening to have removed the engine cover so they can here the whine.

    If I drive my CTS V without that engine cover, I definitely hear the whine more. I prefer not to hear it, so the cover stays on the engine.

    Upgrading the intake will make the supercharger whine a lot louder. 1st mod I'm going to do when I buy mine.
