This universal turbo cross-over tube is offered for those using Holley's turbo manifolds (sold separately) in an application other than supported by the tubes available for specific transmission applications. The cross-over tubes are made from 16-gauge, mandrel bent 304 stainless steel and include a band clamp to attach to one another. 2.25 inch V-band flanges can be welded on to allow connection to Holley's LS turbo manifolds. V-band flanges and clamps are not included with this pipe as they are normally included with Holley LS Turbo Manifolds. These parts work with most common LS swap parts (i.e. motor mounts, swap oil pan, and accessory drive systems) & provide the basic building blocks needed to complete a custom turbo system for your GM LS engine.
