The big gaping hole isn't a resonator...DUH!!!
The thing that's suppossed to be attatched to the big gaping hole is a resonator...DING!!!
I thought that was pretty self-explanitory, but I guess not.
Want to know why your engine has more power and is running smoother now?
You were letting in lots of air that was unmetered (and unfiltered) and causing the engine to run very, very lean. It's a good thing you didn't have any detonation caused by the lean condition, cause you would need more than a film canister to fix your blown engine.
