Whenever, I do a high rev, those weird rattling noise comes. This is a common problems in most RX-8. So what do you guys normally do to solve this prob. Thx..

 

Where does it sound like the rattling is coming from? I have had peoples cars rattle because part of the CAT broke off inside and jumbled around with the vibrations. Then again that was a camaro.

 

*If you know it is a common problem how come you don't know what it is . Put another way - go back to whoever told you it was a common problem and ask them what it is and how to fix it.
*search 'marbles in a can' or 'miac'
*If no luck with that you need to be more specific ie what rpm etc
*1 thread per subject please
