I have recently noticed a rattle from one of my cats. Has anyone else had a rattle from one of their cats?

What brand of cats does Kooks use?

its probably not your cats, its probably your heat shields

 

I also had problems after going to long tubes with rattles, vibrations and such. There were a few long bolts that are close to the shields/cats after installionoflongtubes/catted midpipe and axle back. Everything seems to tuck up a bit higher. After purchasing/install of Steeda HD engine mounts and going over every clearance issue, I now have a totally quiet (other than the sound from the mufflers) exhaust.

The Kooks, from what I've heard, don't have the clearance issues that my JBA's had but you never know. I also think Kooks imploys the metallic cats, so it's not likely you have an internal cat issue.

 

Are you both running the hi-flo catted X with your Kooks LT's?
I am considering this setup but also considering the H.
