IMPORTANT FITMENT INFORMATION
This is NOT a universal factory replacement downpipe. Your vehicle must have a compatible turbo conversion using the correct 5-bolt turbine outlet configuration. Engine code alone does not guarantee fitment. Verify turbo outlet flange, exhaust diameter, downpipe routing, chassis clearance and the remainder of your exhaust system before ordering. Custom installation or fabrication may be required.
Built for Turbocharged Honda Performance
A turbo downpipe carries exhaust gases away from the turbine outlet and into the vehicle's exhaust system. On a modified Honda turbo build, the downpipe is therefore a critical connection between the turbocharger and the rest of the exhaust.
This 2.5-inch configuration is designed for compatible performance turbo systems where the turbocharger uses the matching 5-bolt outlet. It is particularly relevant to enthusiasts building B16, B18, D15 and D16 turbo combinations in Civic, Integra, Del Sol and CRX platforms.
