That is an On3 kit. Going by description that is the original style kit that uses stock exhaust manifolds or shorty headers. I don't even think On3 even sells that kit anymore. They definitely don't list it anymore.

Didn't know on3 included down pipes to catback. So i guess hellion and on3 are my only 2 options for a 4.6 2v 99 gt unless I go custom
