dezmond_vr6 Posted May 3, 2014 Share Posted May 3, 2014 Is ther any way I can change this pitch of the dump valve? They are very high pitch I would like to have it abit more deeper sound if can change it at all. Cheers Quote Link to comment Share on other sites More sharing options...
Gambit Posted May 3, 2014 Share Posted May 3, 2014 Should be able to alter the spring for the pressure to release and the filter inserts to change it. Quote Link to comment Share on other sites More sharing options...
dezmond_vr6 Posted May 4, 2014 Author Share Posted May 4, 2014 Dnt think this one is a spring is it? It seems to already have one filter in looks but like the shape of Mercedes badge. If I took that out should be a more deeper sound would u think. Quote Link to comment Share on other sites More sharing options...
Gambit Posted May 4, 2014 Share Posted May 4, 2014 I would have thought so its a filter so will restrict air out so removing it should make it louder I know you can get other filters for them youtube has video of all 3. And it will work on some sort of spring mechanism to be able to open and close but im not sure how or if it can be set with them ive never owned a hks dump value.
