The Forced Performance S400 CH outlet V-band flange with a 3.5 in ID is a V-band outlet flange sized to 3.50 inches inner diameter for S400-series turbo outlets. It gives fabricators a serviceable V-band interface for exhaust or charge plumbing when a slightly larger 3.50-inch connection is needed, simplifying assembly and maintenance on high-flow turbo systems.
