BD-Power 1041460 Full Bore Exhaust Manifold 842 12.00 BD-Power 1041460 Full Bore Exhaust Manifold
4.5 5 10
$ 165
The BD-Power 1041460 Full Bore Exhaust Manifold will restore the balance to your engines exhaust flow, reduce cylinder load and reduce exhaust gas temperatures. The factory driver side exhaust manifold in your 01-10 Duramax is pinched down to allow for steering shaft clearance that isn't even required! As a result, your exhaust flow is significantly disrupted. The BD-Power Full Bore Exhaust Manifold addresses this issue by maintaining internal bore size. Made from high-silicon ductile iron, the Full Bore is a direct, bolt-in replacement for the factory manifold and is even drilled and tapped to accept the most popular EGT probes. Stock Exhaust Manifold: Only flows 80% of the passenger side manifold 3 cylinders only operate at 80% capacity and load others down No access to measure exhaust temperature BD-Power Exhaust Manfilold: Contaings Exhaust Temperature Probe Port Maintains consistent exhaust pressure and temperature on both sides of the engine Flow matches the passenger side manifold and balances the engines exhaust pressure. Manifold gaskets not included. Additional InformationInstall Sheet
BD-Power 1403802 Passenger Side Up-Pipe 31966 7.00 BD-Power 1403802 Passenger Side Up-Pipe
$ 373.75
The BD-Power 1403802 Passenger Side Up-Pipe is a direct replacement for your 2001-2004 GM 6.6L Duramax LB7, and an off-road, race upgrade on your 2004.5-2015 GM 6.6L Duramax LBZ/LMM/LML. The BD-Power Passenger Side Up-Pipe features a 304 stainless steel construction built with precision cast mounting flanges that eliminate exhaust tubing blowouts. The 304 stainless steel tubing also prevents loss of heat energy and does not corrode like aluminized steel or 409 stainless. The larger bore (1.8" ID) internally shielded 304 stainless steel bellows eliminate the restrictive 1.3" OE bellows maximizing exhaust energy to drive your turbocharger.?Features: 304 Stainless Steel Construction Increased Turbo Response With Lower EGT's Smooth Mandrel Bends Improves Exhaust Gas Flow Application Notes: This Up-Pipe does not have an EGR riser so it is not a direct replacement on 2004.5+ models unless it is an off-road application with an EGR track kit. Direct fit for 2001-2004 LB7 engines federal emissions (non-EGR).
