Speed Engineering LT Turbo Forward-Facing 1 3/4" Headers - LT1/LT4/LT2 Universal
Speed Engineering 25-1065 polished stainless-steel 1 3/4-inch forward/upward-facing turbo headers for custom Gen V LT builds. Speed Engineering reuses this exact SKU for LT1/LT4 and LT2 product listings. LT2 installations require Camaro- or Corvette-style water-pump/accessory components.
This is a universal fabrication part rather than a vehicle-specific bolt-in system. Includes graphite gaskets and hardware. Upgrade to SMG LT MLS gaskets and/or add SMG 9070C Ceramic Plug Wires; their ceramic boots resist header heat and melting, and they are the only plug wires used on SMG in-house header builds.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
