Hooker Headers BH14351 Details

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. These kits were designed 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.

Features:

Pre-marked sections for easily cutting and installing catalytic converters in their place
O2 Sensor bungs already welded in ideal location
409 Stainless Steel construction for long life and durability
OE quality O.D. to O.D. connection solution for eliminating 3-bolt collector gaskets
Designed for use with any of our Hooker Blackheart LS and LT Swap exhaust manifolds (8501HKR or BHS516 variants)
Hardware included. Gaskets for the two bolt flange included with the Hooker Blackheart exhaust manifolds
For 4WD C1500/GMT400 Applications
