Merge Collectors
A merge collector is the critical junction where individual primary tubes join into a single exhaust pipe on a header. Its job is to smoothly combine exhaust pulses into a high-velocity stream, reducing backpressure and enhancing scavenging effects.
Whether you're fabricating a custom header or replacing a damaged collector, this collection covers the essentials: collectors in mild steel and stainless steel, with or without merge spikes, and in various configurations. The transition angle, internal shape, and outlet diameter directly influence torque curve and horsepower.
- Material matters: Stainless steel resists corrosion and handles high heat; mild steel is cost-effective and weldable.
- Merge spikes: A tapered center cone helps guide flow and can improve mid-range torque by enhancing scavenging.
- Sizing: Match the collector inlet count and tube size to your primaries, and the outlet diameter to your exhaust system.
Browse our merge collectors to find the right piece for your build. Need help? Reach out to our specialists for selection advice.
