FlowTech Exhaust Long Tube Headers

FlowTech Long Tube Headers deliver the proven combination of performance engineering and outstanding value that enthusiasts have trusted since the brand's founding in 1994. Part of the Holley Performance Products family of brands, FlowTech has built its reputation as a recognized leader in value-priced performance exhaust — purpose-built for street performance, spirited driving, and real-world power gains without the premium price tag.

Long tube headers are a time-tested upgrade over restrictive factory exhaust manifolds, dramatically improving exhaust gas evacuation to unlock measurable gains in horsepower, torque, throttle response, and fuel efficiency. FlowTech's long tube design maximizes the scavenging effect across the RPM range, delivering an aggressive exhaust note and tangible performance results.

Key Features:

• Mandrel-bent tubing maintains a consistent diameter through every bend for smooth, unrestricted exhaust flow and maximum exhaust velocity
• Formed collectors with fully-welded joints efficiently merge exhaust pulses for improved scavenging and reliable, leak-free performance
• Extra-thick machined header flanges deliver a tight, leak-free seal at the cylinder head for maximum performance and long-term durability
• Slotted port flanges and dimpled tubes provide added clearance at the port for header bolts, easing installation — a hallmark FlowTech engineering refinement
• Leak-tested for maximum performance with precision-engineered fitment and quality welds for lasting durability
• Multiple finish options available depending on application variant — consult individual product listings for finish details
• Complete installation hardware and premium gaskets included for a straightforward bolt-on installation on most applications

Constructed from cold-rolled mild steel or stainless steel depending on application, FlowTech Long Tube Headers are engineered to replace restrictive factory exhaust manifolds and deliver real-world performance gains at an accessible price point. Select the correct variant for your specific application to ensure proper fitment and maximum results.

Important Notes: Breaking in an engine with ceramic-coated headers will result in damage to the coating and will void all warranties. FlowTech does not recommend the use of header wraps, as this will void the warranty. Some applications may require modifications to existing exhaust components.
