Does anybody have any recommendations on what solution works best? I have a GTM stage 1 supercharger on my 40th Z. I just had it retuned and installed Invidia test pipes before the tune. But I can't stand the loud rasp i get at certain RPM's and when I let off of the gas. I contacted Berk and they said their HFC would be ok as long at the tune was not to rich. or should I go with MD ART test pipes, or Fast Intention resonated test pipes? Not sure what would give me rasp free sound and still be good for HP gains. Any help would be amazing! ps sorry for the long post!
