hey guys just a quick question.

when i bought my car a month ago the supercharger whine was a lot louder then it is now. it used to have a 3.4 pulley but no headers so i went back to stock.and yes i understand it would get quieter. i also have a cai but i can like never hear the whine... is there anything i should look into to get back that whine? the filter is a little dirty could that be it? and how would u suggest cleaning it or just get a new one
