Just got done riding my 16 XCT with some adjustable DDT mufflers from @crosscountryla . Pretty much perfect for what I requested. My main request was no drone at all, which he nailed. After that I just wanted something that had some muscle to it but mellower than full on loud pipes, as my wife and I like to listen to music and talk when we ride. It's got an old school throatiness v8 muscle sound to it, and barks when you lay into it, nice grumble on decel with no popping. I actually wouldn't mind it a hair louder, and I have that option given it's adjustability. My wife says it's perfect. I'm a happy customer. Thanks Dave!
