Product Description
The BD DIESEL 1043803 Up-Pipe Passenger Side is a durable, high-performance replacement for the factory exhaust up-pipe on Chevy/GMC 2001–2004 LB7 6.6L Duramax 2500/3500 trucks. Factory up-pipes are known to suffer from corrosion and leakage over time, which can reduce exhaust flow and turbo efficiency. This BD Diesel up-pipe improves exhaust gas flow, turbo response, and long-term reliability.
Constructed from precision stainless steel with internally shielded bellows and mandrel bends, the BD Diesel up-pipe maximizes exhaust energy reaching the turbocharger while resisting corrosion and fatigue far better than the OEM component. Featuring stronger, precision cast mounting flanges, it offers a snug, leak-resistant fit that supports improved turbocharger performance and reduced exhaust gas temperatures.
