Description

Flowtech upright derby style headers (MPN 11587FLT) are designed for GM V6 engines, specifically the 2.8L, 3.1L, and 3.4L variants, accommodating both round and D-port cylinder heads. These headers feature mandrel-bent, 1-1/2 inch primary tubes, which ensure consistent tubing diameters for improved exhaust pulse flow and enhanced performance, including better throttle response. Constructed from heavy-duty 16-gauge 409 Stainless Steel, these headers are built for strength and durability.
