Over time, the factory exhaust manifolds are prone to cracking due to excessive exhaust gas temperatures. BD has solved this prevalent issue with their complete upgraded manifold kit that includes both driver and passenger side manifolds, featuring 75% thicker walls and enhanced flow characteristics for increased power and lower EGT's.
Crafted with heavy duty 0.275" thick-walled Hi-Silicon ductile castings, this makes these manifolds 75% thicker to combat cracking due to high exhaust temperatures. Thermal durability has been improved with longer exhaust studs and spacers plus thicker, more durable machined bolting flanges. To maximize exhaust flow, computational fluid dynamics were used to optimize flow and exhaust port sizes have been increased to match gaskets.
Fully EGR compatible, BD's exhaust manifold set is the perfect replacement for reliability, performance and peace of mind.
