The most distructive level of detonation that takes place at full throttle you will never hear even with closed exh, but you would have sure as hell seen it on your spark plugs if you knew what to look for , or even first off knew how to determine if you even had the needed heat range of plug in your motor for it to live at full throttle time after time.
If a motor is on the edge with jetting at full throttle and you combine that with a wrong heat range plug your guaranteed to have issues.
