Replaces the factory exhaust up-pipes
(exhaust manifold to the turbo) which are prone to leakage due to
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 PowerStroke problem and are perfect as an upgrade
while performing other engine or transmission repairs.

Ductile cast iron Y-pipe design is a perfect fit and eliminates leaks and
weld failures
Larger diameter 304 stainless steel uppipes includes internally shielded
