right manifold 340/360

You said "center dump"..........even the 2 1/4" 340 passenger manifold doesn't dump in the center, it kicks back at an angle. The passenger 318 manifold (1 5/8") and the 70s 340 passenger manifold (1 7/8") are center dump but I know of no other "passenger" manifold that is center dump AND two inch diameter. You'd save money buying a 96/97/98 Jeep Grand Cherokee passenger's manifold (2 1/8)...however it is not center dump but it does have great clearance!!
