Description
BD Duramax Up-Pipes Kit Chevy/GMC 2001-2004 LB7 Replaces the factory exhaust up-pipes (exhaust manifold to the turbo) which are prone to leakage due to the deterioration. BD up-pipes are designed to minimize restriction to the turbo utilizing internally shielded expansion bellows. The BD up-pipes are a durable, longer-life replacement for this common problem and are perfect as an upgrade while performing other engine or transmission repairs.
- 304 stainless steel precision cast mounting flanges eliminate exhaust tubing blowouts and ensures correct fitment
- 304L 2-inch stainless tubing prevents loss of heat energy and will not corrode like aluminized steel or 409 stainless
- Internally shielded 304 stainless bellows
- Increased turbo response with lower EGT’s
- User must have aftermarket downpipe, does not fit with OE Downpipe
