BD Diesel BD Duramax Up Pipes Kit Chevy/GMC 2001-2004 LB7 1043800

Replaces the factory exhaust feed system (exhaust manifold to the turbo) which is prone to leakage and escaping exhaust and heat from the deterioration eventually burn out the feed pipes causing loss of turbo drive pressure and increased EGT's. New designed piping with sizing to maximize transfer of heat energy to the turbo come with less restrictive, internally shielded expansion bellows that are not exposed to exhaust gases thus reducing the chance for burn out.
