All i can say is that if you're looking for quietness, you're best off buying a new stock intake from the dealer. Especially how you said you dont care about performance. Any aftermarket intakes regardless of cold air, short ram will sound a WHOLE LOT louder than your car with the stock resonator off. Intakes are made to increase performance (something you dont care about) and therefore do not emphasize on reducing engine noise. Any aftermarket intake will be a lot louder than ur stock resonator removed, so id suggest that you purchase a new stock intake components from the dealer. Hope that helps.
