BD Diesel Passenger Side Uppipe 2001-2004 Chevy/Gmc LB7 Duramax

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
• Larger bore (1.8" ID) internally shielded 304 stainless bellows, eliminates restrictive 1.3" ID OEM bellows maximizing exhaust energy to drive turbocharger
• Smooth mandrel bends improve exhaust gas flow - tubing ID is not compromised
• Increased turbo response with lower EGT's
• User must have aftermarket downpipe, does not fit with OE Downpipe
