Chevy / GMC 6.6L Duramax Big Bore Manifold
Increases exhaust flow by 20%
BD "Full Bore" Exhaust Manifold
You can easily remove the final restriction in your exhaust
system by replacing your factory exhaust manifold with a BD
Power exhaust manifold. Dyno testing has shown that these flow
more efficiently and will increase power, lower exhaust gas
temperatures (EGT's) and improve your fuel economy.
Improve
exhaust flow, reduce exhaust gas temperature (EGT) and realize
greater power gains with the new "Full Bore" driver's
side exhaust manifold for the '01-'06 GM Duramax.
You may
not know it, but the factory driver's side manifold is pinched
down to allow clearance for the steering shaft, which actually
isn't required. As a result, this manifold flows 80% of the
passenger side manifold. The BD Full Bore exhaust manifold
restores exhaust flow to match the passenger side, and is
a direct, bolt-in replacement for the factory part (GM gasket
required). The BD Full Bore manifold is made from high-silicon
ductile iron to resist cracking from high temperature and
vibration, and is even tapped to accept the most popular EGT
probes.
The BD
Big Bore exhaust manifold is a great compliment to BD's new
SuperMax turbo upgrade kit and stainless steel X-Hale exhaust
systems.
