Some of ya'll may recall when I traded in my '12 KP for my CCT I came on here and mentioned that it's not close to being as fast as my KP was (stage 1 was about it). Well I went on a small spending spree and ordered up the AFR+ (Rylan's comments sold me on it), Lloydz ATS, Lloydz Hi Flow filter and Lloydz 1/4 turn throttle. Install went fairly smooth. I started the ATS at 6+ and so far no ping, I'll ride it like this for a while and if I continue without ping, I may bump it to 8+. I took a small test ride and wow, I'm not sure which is giving me the best bang but there is a completely noticeable power gain. Very noticeable! I believe I've just caught up with and maybe even past the acceleration of my ole KP. Some more riding will be in order. Oh...I'm also running stock exhaust and don't plan on changing it. LLoyd says the stock exhaust on the X bikes are very good and I enjoy the music and chattin' with the ole lady.
