So I have a stock 13 challenger r/t . Just installed a jba Catless mid along with dynomax mini bullets. bot muffler and res. deleted. When I start it up its has the deep, throaty sound I like, but when I press down on the gas and the rpms go up the loudness fades into super high pitched tone. when I go to give it some power it sounds like a high pitched machine gun. Im just wondering what you all would recommend me do to go from an annoying metallic like loud to a more aggressive pure sounding loud when accelerating.. honestly the louder the better drone or not I simply want the loudness to keep increasing the more I accelerate. im a fan the rasps crackles and pops but it has to sound good. id like to know, first, stuff I could add on or take off that wouldn't cost a lot or even if a tune will fix the problem but would alsonlove some input on other routes I could take later on such as headers, Catback exhaust ect. that could get me the sound im after!
