AGP has released this billet turbine outlet v band flange to adapt the standard 3.625" OD (outside diameter) turbine housings. If you have a Garrett, Turbonetics, Precision, or AGP Turbo turbine housing, you are able to easily make your 3.5" or 4.0" downpipe, without any transitions or custom fabrication.
Constructed of 304 stainless steel, the inside of the flange allows you to weld your 3.5" tube while the outside of the flange is designed to have your 4" tube slide over for welding. We offer this as a flange by itself, or as a kit with the corresponding clamp.
