These are Speed Engineering’s C10 swap manifolds that work great in the XJ.
GM LS engine swap applications where durability and leak-free sealing
Less Valve noise than traditional shorty or longtube headers
2.25 inch outlet diameter offers improved flow for maximum performance from a cast iron exhaust manifold
2 bolt exit flange configuration matches the E-rod exhaust manifolds for a factory like fitment. This allows the use of factory gaskets and fasteners if desired, for an original quality seal and fitment
Tight tuck design provides universal fit for most popular chassis and a clean traditional muscle car appearance
Note: Some clearancing may be needed to allow ideal fit depending on the setup of your Jeep’s conversion. If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance.
