my last one did that, it was an apexi onei to would like to have a listen as ill be needing a new one shortly...
I had a blitz before my fmic, and i thought it sound the same as the standard..
I would like a really low low tusch sound not a tisch...
my ones been blanked off and has no dump valve but it recirculates through the filter and you get an awesome flutter sound... been told it sounds like the cars sneezing??? its not a tusch or a tisch, just lasts a long time and it sounds like its sneezing!!!
