Overview

Flowtech headers are designed to enhance performance while offering excellent value. These shorty headers are precision-engineered with mandrel-bent tubing and formed collectors, ensuring smooth exhaust flow and increased velocity. They feature durable 3/8" flanges for a leak-free seal and are constructed from heavy-duty 16-gauge mild steel tubing for strength and longevity. The headers are coated in a high heat-resistant black paint, providing a stealthy appearance and added protection. Included premium aluminum header gaskets facilitate a simple and secure installation. With 1.625-inch diameter primary tubes, these headers improve exhaust flow, boosting performance and throttle response for a more engaging driving experience.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
