BD Diesel passenger-side up-pipe for 2001–2004 Chevy Duramax LB7 6.6L replaces the factory exhaust up-pipe with internally shielded expansion bellows and 304L stainless tubing. The precision cast mounting flanges reduce exhaust blowouts while smooth mandrel bends maintain tube ID for improved flow. This durable, longer-life replacement requires an aftermarket downpipe and is designed as an upgrade during related engine or transmission repairs.
