This system produced gains of up to +14 HP and +15 lbs. x Ft. TQ., as measured on our in-house dyno. This system is constructed of 1-5/8 IN mandrel-bent 409 stainless steel tubing for maximum strength and durability. Factory style laser cut machined mild steel flanges are used used for a secure leak-free seal. 3-to-1 Mitered Merge collectors decrease turbulence and increases exhaust velocity. The result is increased horsepower, torque and improved throttle response. Includes gaskets and lower outlet hardware for a direct bolt-on system. No cutting or modifications required for a hassle-free installation. Utilizing state-of-the-art computer-aided design technology, these headers are designed for custom, high tolerance factory fitment. 100% MIG-Welded for race-proven strength and durability.

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.
