These Adapter Pipes are a great start when trying to connect Hooker Blackheart LS/LT Exhaust Manifolds to a catalytic converter and Hooker Blackheart exhaust system. The BH14351 best fits 4WD GM C1500 "OBS" projects that are planning on running a set of Hooker Blackheart LS or LT swap exhaust manifolds (8502HKR, BHS518, etc.) and need a great adapter piece to accomplish two things: 1) fill the gap between the end of the manifold and 2.50-inch inlet exhaust systems and 2) easily incorporate a catalytic converter.
