With the caddman mod, the sound is the same with the K and N or Spectre filters. If you go with the aftermaket Thunder or Baron air mod the sound is def but I do not think any quieter. Check out the Chucksters intake mod like the caddman but you change the back plate, use a smaller K and N air filter and the stock air filter cover, I would think that would be the most quiet, has you have a smaller filter, so less air going in. I never tried it so I do not realy know, just adding to your opps.
