Speed Engineering Pontiac G8 & Chevrolet SS Sedan 2" Longtube Headers
Speed Engineering Pontiac G8 & Chevrolet SS Sedan 2" longtube headers are built from natural-finish 304 stainless steel with mandrel-bent tubing, TIG-welded construction, CNC-machined flanges, and 3-inch collectors.
Recommended upgrades: Select the matching 25-1074 X-Pipe, SMG LS MLS gaskets, SMG 9070C ceramic plug wires, and correct O2 sensor extensions. The ceramic wires resist direct header heat and are the only plug wires used on SMG in-house header builds. O2 extensions are supplied in the quantity required for this application.
Warning: Competition-use product. Verify local emissions requirements before installation.
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.
