How do you go about the cat delete? I have emailed just about every US and UK parts dealer looking for a cat by-pass or decat box etc and no one has one for sale? I tried to get my dealer to do it but they said they can't touch it. They are happy to re-tune the bike once it is modified but can't sell me anything to remove replace it. I also have a 2015 model so maybe that is the difference??? I want my X to sound a little more aggressive just not HD annoying. I did just order the K&N filter kit that requires cutting of the bearclaw. I am told the "sucking sound" they will now create makes for a unique sound but still not a rumble.
