Eliminate the costly exhaust manifold cracks prevalent in the
factory exhaust manifold. The aFe BladeRunner exhaust manifold
sets the new standard for quality, performance and longevity.
It outflows the factory exhaust manifold by up to 23% resulting
in increased throttle response and lower EGT's. The thick wall
(0.25" vs. 0.15")T3 flange design increases strength,
eliminating warping and cracking prevalent in the factory
exhaust manifolds. The matched ports and merged runner design
reduces exhaust backpressure, maximizing exhaust flow. Once you
install this exhaust manifold, you will feel quicker
turbo spool up times, improved throttle response and increased
• Outflows the
factory exhaust manifolds by 6%, improving performance and
• Compatible with factory
up-pipes which allows for easy installation.
• Eliminates the flow
restricting pinch of the factory drivers-side manifold
• The machined ports match
the factory gasket openings which maximizes exhaust flow
• 1/8" NPT exhaust gas
temperature ports (EGT) ports are incorporated into the exhaust
manifolds for gauges or testing equipment
• Durable cast ductile iron
• Manifold mounting hardware
is included for a hassle-free installation.
These manifolds have both the inlet and the outlet ports
machined to match the factory gaskets. This allows for maximum
flow, without compromising gasket performance.
An Exhaust Gas Temperature (EGT) probe port is incorporated into
each manifold for easy installation of gauges or testing
equipment. There are three additional cast in bosses provided to
allow for alternate testing points.
These manifolds are compatible with the stock up-pipes, which
allows the manifolds to be installed without having to remove
the turbocharger down-pipe or the up-pipes.
