Fitment Notes

• Fits 2004.5 (mid-year 2004 Common Rail production) through 2007 models ONLY - does NOT fit 2003-early 2004 Dodge Ram trucks equipped with the VP44 injection pump, which use a different turbocharger and turbo elbow design
• Compatible with both the factory OEM stock turbocharger and the BD Diesel Screamer performance turbocharger
• Not compatible with 2007 early-production trucks built with the 6.7L Cummins - confirm engine type before ordering
• V-Band clamp not included - see BD Diesel part number 1045101 if V-Band clamp is required

Features

• Cast iron construction engineered to withstand the extreme heat and pressure generated at the turbine outlet of a high-boost diesel turbocharger
• Direct-replacement turbine outlet exhaust elbow - restores OEM-equivalent fitment and flow routing when the factory elbow is cracked, damaged, or compromised
• Compatible with both the factory stock turbocharger and the BD Diesel Screamer performance turbocharger - making it the correct elbow for Screamer turbo installations on 2004.5-2007 5.9L platforms
• Designed for correct exhaust gas routing from the turbine housing to the downpipe - maintains factory exhaust alignment and eliminates the need for custom fabrication
• Durable cast construction resists cracking, warping, and fatigue caused by thermal cycling and high exhaust gas temperatures
• Vehicle-specific fitment ensures proper alignment with the 5.9L Cummins Common Rail turbocharger mounting and downpipe connection points
• Legal for sale and use in all 50 U.S. states by nature of its replacement-part design

Product Description

The BD Diesel 1045100 is a cast iron turbocharger exhaust elbow - also called the turbine outlet elbow - engineered specifically for 2004.5-2007 Dodge Ram 2500 and Ram 3500 trucks equipped with the 5.9L Cummins Common Rail turbocharged diesel engine. The turbine outlet elbow is the cast component that bolts directly to the exhaust side (turbine housing outlet) of the turbocharger and routes spent exhaust gases into the downpipe and the rest of the exhaust system. On the Common Rail 5.9L Cummins platform, this elbow is exposed to extremely high exhaust gas temperatures and significant thermal cycling, making it a known failure point - particularly on high-mileage trucks or on trucks that have been tuned for increased output. A cracked or warped stock elbow can cause exhaust leaks, elevated EGTs, power loss, and damage to surrounding engine bay components.

What makes the 1045100 particularly versatile is its compatibility with both the factory OEM turbocharger and the BD Diesel Screamer performance turbocharger. For owners upgrading to a BD Screamer on the 2004.5-2007 5.9L Cummins platform, this cast elbow is the correct turbine outlet component to complete the installation - BD Diesel's own Screamer turbo installation documentation specifically identifies part number 1045100 as the required turbine outlet exhaust elbow for this application. The cast iron construction is purpose-built for the thermal demands of the turbine outlet position, offering resistance to cracking and warping that sheet metal or lower-grade alternatives cannot match.

Installation is straightforward for experienced diesel technicians familiar with turbocharger service on the 5.9L Cummins. The elbow mates to the turbocharger turbine housing outlet and connects to the downpipe using the vehicle's existing mounting hardware. Owners requiring a V-Band clamp along with the elbow should refer to BD Diesel part number 1045101, which includes the V-Band clamp as part of the kit. The 1045100 elbow alone is the correct choice when replacing a damaged factory elbow while retaining the existing exhaust hardware. It is important to confirm the 2004.5 build date distinction - early-production 2004 Rams used the older VP44 injection pump system with a different turbocharger configuration and are not compatible with this elbow. Backed by BD Diesel's limited lifetime warranty, the 1045100 is the definitive cast turbo exhaust elbow for the 5.9L Common Rail Cummins platform.
