FlowTech Exhaust Mid-Length Headers

FlowTech Mid-Length Headers deliver the ideal balance of performance and value for enthusiasts looking to replace restrictive factory exhaust manifolds. Founded in 1994 and now part of the Holley Performance family, FlowTech has built a strong reputation as a leader in value-driven exhaust solutions — offering professional-grade engineering without the premium price tag.

The mid-length header design strategically bridges the gap between short-tube and long-tube styles, optimizing exhaust scavenging across the full powerband for measurable gains in both low-end torque and top-end horsepower. Each header is precision-engineered for application-specific fitment, ensuring a secure, factory-style installation.

Key Features:

• Mandrel-bent tubing maintains a consistent diameter throughout for smooth, unrestricted exhaust flow and maximized exhaust velocity
• Heavy-duty flanges are precision-ground for a tight, leak-free seal at the cylinder head
• Tube dimpling at the port provides added clearance for header bolts, simplifying the installation process
• Mid-length design optimizes exhaust scavenging across the full RPM range for broad powerband gains
• Available in multiple finish options to suit different performance builds and aesthetic preferences
• Complete hardware kit included — all necessary mounting hardware and gaskets provided for straightforward installation
• Factory leak-tested prior to shipment to ensure maximum performance and long-term reliability

Whether you're building a classic muscle car, a street machine, or a weekend performance driver, FlowTech Mid-Length Headers provide a proven, cost-effective foundation for your exhaust system upgrade. Engineered to deliver real performance results, these headers are a trusted choice among enthusiasts who demand quality at an accessible price point.
