Speed Engineering Cadillac CTS-V 2" Longtube Headers 2009-2015 are built from natural-finish 304 stainless steel with mandrel-bent tubing, TIG-welded construction, CNC-machined flanges, and application-matched collectors.
Recommended upgrades: Select the matching 25-1049 exhaust connection, SMG LS MLS gaskets, and SMG 9070C ceramic plug wires. The ceramic wires resist direct header heat and 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.
