I don't hear exhuast under my door though, only from the back. and I have never had a CEL come on.

would this indicate a exhaust leak or just the nature of the pipes?
most likely the seal is broken. If you give it gas while idling, you can hear it sputtering while the rpm drops, more like you're blowing a piece of paper.
But you've the version 3, so why use the RTV and not the ring gasket?
