        I know the jeep srt manifolds work with an aftermarket k frame. The car manifolds face the pipes into the firewall so they will not work. I believe someone used a combo of jeep/ ram 5.7 logs but don’t remember who it was

        If they are the car ones then they will not as they dump directly into the firewall.

        That is why I love this site! The folks on here are a wealth of info. Toplscuda just saved us both some aggravation! They are a Car set from a Challenger! I think I will make yard art out of them.

        A member named Gdemon used some sort of factory manifolds, I think Jeep, the drivers cleared but the pass side he had to notch the frame around the manifold if I remember... try a search with his name, I think he posted pics way back when...

        In my opinion though the proven Dyno gains with headers alone over the factory logs make the headers a no-brainer even with the stupid cost.

        The Jeep manifolds compared to the car manifolds stay tucked next to th e block....a big plus for an A body install..
