Part number
46-40011 represents the latest in airflow technology from aFe. The
all new BladeRunner exhaust manifold is constructed out of .25”
thick wall, cast 304 stainless steel for maximum durability under
high heat conditions as compared to cast iron units. 46-40011 features
a merged runner design for smooth exhaust transitions and increased
flow. This manifold also comes with 2-EGT probe ports to provide
you with the ability to measure EGT’s on both banks of the
exhaust manifold. The EGT ports are positioned inline with the air
stream as to not disrupt the exhaust flow. 46-40011 is a one-piece
design and has re-enforced ribs between each exhaust port to increase
the strength and eliminate the cracking found in most stock and
aftermarket units.
In recent testing,
part number 46-40011 increased exhaust flow by 23% over the
stock exhaust manifold improving throttle response, lowering
EGT’s.
