Prior to this bike I had a speed triple and before that a valkyrie. I love the duke but I've read they run lean and I want a smidge more power. I found a full titanium exhaust on ebay and the guy has all positive reviews and sent lots of pictures but I'm still worried about fitment plus most aftermarket full exhausts still have the mid pipe resonator and I don't want something absurdly loud. Have any of you guys used it? Link below. Also what kind of tune are you guys running with a full exhaust and airbox mod? Well turns out I can't post a link but this is the auction number: 133083675232
