Hooker BlackHeart Gen V LT Rear Dump Exhaust Manifold Pair SBC-Style Exit 2.5" Outlet Black Ceramic Coated

Installing GM Gen V LT engines into chassis originally designed for Small Block Chevy exhaust layouts can create exhaust routing and clearance challenges. This Hooker BlackHeart rear dump exhaust manifold pair uses an SBC-style outlet position to simplify exhaust fabrication while maintaining improved clearance in compact LT swap applications.

Features and Benefits:
 - SBC-style exhaust outlet position
 - Black ceramic coated finish
 - Rear-dump manifold configuration
 - 2.5” outlet diameter
 - High-silicon-moly cast iron
 - Improves exhaust routing flexibility
 - MLS flange gaskets included
 - Nickel-plated mounting flanges

Constructed from high-silicon-moly ductile cast iron, the manifolds feature a tight-tuck rear-dump configuration that positions the outlets between standard swap and center-dump layouts. Contoured internal passages help improve exhaust flow and reduce turbulence while the black ceramic coated finish helps lower engine-bay temperatures and improve corrosion resistance. The 2.5” outlets support performance exhaust systems without sacrificing frame or ground clearance. Nickel-plated steel flanges, MLS gaskets, and mounting hardware are included for installation.

Applications:
 - GM Gen V LT-Series engines
 - LT engine swap
* Not compatible with 2004-2006 Pontiac GTO starters/bellhousings

Please Note:
 - Designed specifically for GM Gen V LT engine swap applications.
 - Ceramic-coated manifolds require multiple head cycles to fully cure.
 - Head shielding is recommended near sensors and wiring.
 - Exhaust routing and connection components sold separately.
 - Verify chassis, steering, and frame clearance before installation.
 - Professional installation is recommended.
