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 turbo Y-adapter is made
from high-silicon ductile iron. 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.

Prevents loss of turbo drive pressure and increased EGT’s
Crush donuts replaced with stainless steel gaskets for extended sealing
life
Maximizes transfer of heat energy to the turbo
Less restrictive, internally shielded expansion bellows
Reduces the chance for piping burn out
