Hooker Blackheart LS Swap Exhaust Systems for 1988-2000 GM “OBS” Trucks/SUVs
These Hooker Blackheart exhaust systems are ideal for both 2WD and 4WD GM “OBS” projects that are planning on running a GM LS or LT engine, but will work with nearly any V6 or V8 engine in this chassis. Also available to complete your exhaust systems are optional stealth exit (BH14352) and rear exit (BH14354) exhaust tip kits. For a complete swap solution, look into Hooker Blackheart swap exhaust manifolds (8502HKR, 8503HKR, BHS516, etc.) and adapter pipe kits BH14350 and BH14351 to accomplish two things: 1) fill the gap between the end of the manifold and 2.50-inch inlet Hooker Blackheart exhaust system and 2) easily incorporate a catalytic converter.
These kits were designed to all work together and for compatibility with Hooker Blackheart engine mounting brackets listed for this vehicle application only. They are designed to provide the user with a means of installing the factory catalytic converters from a 1999-2006 5.3 or 6.0-liter Chevy Silverado truck (4.00-inch maximum diameter), into this vehicle application, within the stipulations/requirements published by CARB/EPA for emissions-legal engine changes. The ability of the final fabricated assembly to satisfy these requirements should be confirmed with local/state authorities prior to the installation of these components.
