I know it sounds strange, but when I use 93 octane gas, my car seems to quiet down. Do you think I might have clogged cats? I know I have the stock H pipe, but it never fails, when I use a lower octane, my car sounds louder. Maybe I'm nuts.

I have noticed extreme sluggishness lately. Probably because I am used to the car and need some mods. Gear, O/R Pipe, Chip, and T/A sound good. Now I need a couple of grand!

Maybe some build up is causing semi detonation or something? I don't know if it's possible but higher octane would fix detonation so maybe

Related note, has anyone ever seen dyno sheets for the same car with 87octane then drained and flushed then dynoed with 91-93 octane? Someone told me that higher octane rated gas has less chemical energy stored since some of the volume is taken up by the increased octane.
