HK8517 - HOOKER CROSS-OVER TUBE 2.250" DIAMETER FITS GM LS TURBO

Holley's new LS Turbo Exhaust Manifolds are made from cast iron and allow a simpler and easier way to add a turbo to your muscle car. These manifolds are made from High-Silicon-Moly ductile iron and are much more durable& retain more heat than fabricated headers. The manifolds kits include v-band clamps& flanges,heater hose heat shield,and header bolts. A turbo cross-over tube is used to connect the two manifolds (sold separately). Choose the cross-over tube based on the transmission (and bell-housing) for optimal fit and ground clearance. The cross-over tubes are made from 16-gauge,mandrel bent 304 stainless steel and v-band flanges welded on for an easy bolt-on fit. A universal cross-over component kit is also available for custom applications that need something a little different (requires fabrication& welding). 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
