Hooker BlackHeart LT Swap Exhaust Manifolds - Rear Dump - Black BHS5194

Multi-Fit - GM Gen V LT Engines - 2.50-in. Outlet. For applications or projects where our standard Gen V LT swap manifolds (BHS516 and BHS3116 style) don't quite fit and our "center dump" manifold (BHS5188) exits too far forward, our new "rear dump" cast iron swap manifolds have arrived. These differ in that they exit in a straight-down fashion much like a block hugger header but exit more toward the rear of the engine than our "center dump" manifolds. Cast out of the same Hi-Silicon-Moly Ductile Iron as most of our other lines, it will be tough to find a more durable, streamlined, and quiet exhaust option. Available in natural cast, silver ceramic, or black ceramic finishes, these manifolds are offered with flanges, gaskets, and flange hardware for connecting to our lineup of adapter pipe kits. This not only allows for the easy addition of catalytic converters but also makes it simple to connect to our many exhaust system options.. Breaking in an engine with ceramic-coated versions of these manifolds will most likely result in damage to the coating and VOID all warranties providing coverage to it. HOOKER™ recommends using bare cast-iron manifolds or an old set of headers to break-in engines to avoid coating damage. _x000D__x000D_Ceramic-coated manifolds require several heat cycles to fully cure before they will withstand extreme heat, so care should be taken to provide a series of 4 to 5 intermittent heat cycles to "set" the coating prior to putting the vehicle into service. An incremental increase in run duration and throttle angle should be added to each successive cycle; initial and final run durations between approximately 1 and 7 minutes will be sufficient to set the coating._x000D__x000D_Certain engines with the knock sensors on the sides of the block: passenger side will need to be clocked for extra clearance. Unplug the sensor by pulling the gray clip back and pressing in the center. Use a 13mm wrench to loosen the knock sensor and turn as shown in instructions. Once complete, be sure that the wire is away from the manifold. Heat sleeve or tape is recommended at a minimum or use Hooker BHS519 heat shield for best results.
