Part #: BH14345
This Hooker Blackheart exhaust system is ideal for 2WD (4WD is available - BH14348) GM C1500 OBS projects that are planning on running a GM LS or LT engine but will work with nearly any V6 or V8 engine swap for this GMT400 chassis. Pair with swap exhaust manifolds (8502HKR, 8503HKR, BHS516, etc.) and adapter pipe kit BH14350 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 parts were intended to 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.Although listed as ending in 1998, this exhaust will fit the classic trucks and SUVs that continued on into 2002 with the same GMT400 chassis.For 2WD C1500/GMT400 Applications - Regular Cab Short Bed - 117.5 Inch WheelbaseOE quality O.D. to O.D. connection solution for eliminating 3-bolt collector gaskets409 Stainless Steel construction for long life and durabilityDesigned for use with any of our Hooker Blackheart LS and LT Swap exhaust manifolds (8501HKR or BHS516 variants) and adapter kit BH14350Hardware includedDetails:Application: 1988-2000 GM OBS Truck SUVDrive: 2WDEmission Code: 8Engine: GM Gen III/IV/IV (LS/LT)Exhaust Series: Hooker BlackHeartFinish: NaturalInlet Diameter: 2.5Material: 409 Stainless SteelOutlet Diameter: 2.5Product Type: Exhaust SystemSystem Type: SwapTube Diameter: 2.5 inchWarning: California Proposition 65Wheelbase Length (in): 117.5
