SB EXT. MANIFOLDS QUESTION
They came on all magnum v8 engines in dodge trucks and vans, I'm not sure what years (or models) have the 2.5" outlets do a seach on this. Go to a boneyard they can be had for 20 bucks. Be sure to port match the manifolds to your heads and keep in mind they exit toward the back of the heads but I personally had no clearance issues. FYI there are a lot headers available that are much cheaper then Dougs, and long tube headers will make more power. I personally hate headers as they create a lot heat, they hard the install, and the always leak eventually. I'm running manifolds and because I have a driver, and yes I'm probably loosing a little power but they so much easier to deal with in imo. If I was racing that would be a different story.
