We've been asked to build a top mount so here it is. Available in T3, T4 and v-band turbine configurations. The production version of this manifold will come standard with a CNC billet collector. For people looking for make more than 600whp or just want a higher grade stainless, 321 stainless runners are an optional upgrade. Hot parts kits are available if you send in your turbine housing. Requires removal of AC and Power Steering as well as relocating the alternator.
