My understanding is the "plus" provides a warranty to the engine if any damage occurs due to the flash, but only allows for 91 octane use. The straight Stage 1 flash has no warranty but can do multiple octanes. Any comments?

I created the video to fill what was a gap in the available information when I was trying to figure out what in the hell I wanted to do with my exhaust system. For those who may be considering cutouts, you ARE NOT WRONG!

Want your exhaust loud and rowdy, push one of your HomeLink buttons. Want it zipped up and distinguished, push another of your HomeLink buttons (yes, I programmed the cutouts to the HomeLink garage door openers).

Check them out! BTW, there are bookmarks in the video description that will allow you to jump to specific sections.
