    Product description

    This Alpha race full catless downpipe unlock full potential of VR30 twin turbo engine by removing factory catalytic flow bottlenecks:
    1. Heavy-Duty T304 Stainless Construction
      3-inch smooth mandrel bent tubing with full leak-proof TIG welding, thicker flange plates for high-temp durability. Polished mirror finish optional, far higher flow than narrow stock 2.5" factory pipes.
    2. Full Catless Race Design
      Complete delete of both primary and secondary OEM catalysts, lower exhaust gas temperature by 100–200°F to protect turbos. Factory-position O2 sensor bungs, optional wideband AFR bung for dyno tuning.
    3. OEM Exact Plug-and-Play Fitment
      3D scanned chassis contour matches original turbo v-band flanges, mounting brackets and undercarriage clearance. Fits both RWD & AWD Q50/Q60/Nissan Z, no cutting or chassis modification required, full gaskets and hardware included.
    4. Significant VR30 Performance Gains
      Dyno proven +20+ wheel HP with matching Alpha ECU tune, sharpen low-end torque and eliminate twin turbo lag. Delivers deep aggressive exhaust tone with crisp throttle overrun crackles at wide open throttle.
    5. Race Only Tuning Support
      Designed for closed track/off-road competition use only; custom ECU tune required to clear check engine light. Perfect matching upgrade with aftermarket intercoolers, cold air intakes and cat-back exhaust systems.
