Proflow Exhaust Manifolds, For Holden / Chev LS Series Engines, High-Silicone Ductile Cast Iron, Black Ceramic Coated, Pair - PFEEH8501BKC

Part Number: PFEEH8501BKC

Proflow's LS cast exhaust manifolds have been designed to hug close to the engine block so they fit into a wide variety of replacement engine swap applications. Their contoured design aims the exhaust directly at the exit port to increase flow characteristics. They are cast from high-silicone ductile iron to provide durability, strength and produce less noise than conventional headers. They also use 304 stainless steel mating flanges to reduce warpage, and a 2-bolt exit flange which can be used with OEM style gaskets and fasteners. These are recommended for strong performance with engines producing up to 500 HP and come in a variety of finishes including raw, black or ceramic coated for reduced header temperatures.

Note: Oxygen sensor extension cables may be needed.
