Note: There are many sizes and types of exhaust flanges. This is the "standard" flange for the exhaust pipe-to-turbocharger connection on many vehicles.
However, it may not fit your vehicle.
Please contact us with your application information and dimensions so we can send you the correct flange.
If you are trying to connect two flanges together, you need special double-rolled flat-faced flanges and the matching V-Band clamp. That assembly is called a "stack breaker" and can be seen on the Exhaust Flanges page.
