here is a pic to show how the supplied bracket attaches to the bottom hole left open when you remove the factory muffler brace ( bottom finger pointing to the hole ). One bolt goes here, the other slides into the Viper. I painted the head of the Fuggin bolt, cause with it being steel on black frame it just stuck out like a sore thumb.
looking down onto the bracket.
this info alone will save you as much as an hour trying to figure out how the hell these pipes install.
