The Forced Performance S400 CH outlet V-band flange with a 4.00 in ID is a heavy-duty V-band flange sized to fit 4.00-inch inner diameter piping on S400-style outlets. It’s intended for high-flow turbo setups requiring a larger V-band connection, making exhaust routing and component swaps easier while maintaining a leak-resistant joint for demanding street or track applications.
