Stainless Steel Construction: The headers are constructed out of heavy duty gauge, mandrel-bent 304 stainless steel tubing with a.120 Inch wall for strength and durability. The up-pipes and down-pipe are constructed out of 2 Inch and 3 Inch mandrel-bent 304 brush finished stainless steel tubing. Optimized Tube Lengths: Tube lengths and mitered collectors are optimized for true pulse control technology which improves flow and performance across the power band.
Heavy-Duty Flanges: A CNC-machined v-band inlet flange and heavy-duty outlet flange provide a secure, leak-free seal. Egt Ports: Two exhaust gas temperature (Egt) ports are provided with this system. A 1/8Сњ Npt Egt probe port is incorporated into the drivers side manifold and a M14x1.5 port in the down pipe.
This allows for easy installation of sensors, gauges or testing equipment. 4 Inch Interlock Flex Pipes: The up-pipes utilizes heavy duty 4 Inch flex tubes with internal interlock liners. Retains EGR Flange: This system retains the EGR flange.
