BD Diesel 1043800 Up-Pipe Kit

The BD-Power 1043800 Up-Pipe Kit increases both performance and reliability in your 2001-2004 GM 6.6L Duramax. Built from 304 stainless steel, these Up-Pipes feature precision cast mounting flanges that eliminate exhaust tubing blowouts. The 304 stainless tubing also prevents loss of heat energy and does not corrode like aluminized steel or 409 stainless. The larger bore (1.8" ID) internally shielded 304 stainless steel bellows eliminate the restrictive 1.3" OE bellows maximizing exhaust energy to drive your turbocharger. Aftermarket downpipe required.  FEATURES:  304 Stainless Steel Construction Increased Turbo Response With Lower EGT's Smooth Mandrel Bends Improves Exhaust Gas Flow  Installation Notes: Requires Aftermarket downpipe, will not work with OE downpipe (not included).  Due to clearance issues, downpipe must be modified, or "clearanced" for proper fitment with up-pipes. Intended for use on BD and factory GM manifolds.  Vehicle Applications: 2001-2004 CHEVY SILVERADO 2500 HD/3500 6.6L DURAMAX LB7 2001-2004 GM SIERRA 2500 HD/3500 6.6L DURAMAX LB7 Not available for sale in the state of California.
