Rev Match Downshift Noise

[Wieb27]

Anyone else hear a noise in what I believe to be the catalytic converter when rev match downshifting? It sounds like a rattle or something moving around in it (and also sounds like garbage too)...

Gut the cat= no more noise.

LOL sorry man, I gutted the cat within the first 3 thousand miles. Its not too bad to do, and it sounds a lot better with it removed. Hope someone else can help you identify your noise.

Did you gut it while the header was still on the bike or did you remove completely? I'm still wanting to gut mine.
