SPDZ1 K-Series K20/K24 Megaphone 4-1 Tri-Y Header – 2-Bolt Collector | For EG, EK, DC2 K-Swap Builds

Track-Proven Power. Street-Friendly Design. Race-Ready Results.

Built for serious K-series swappers, the SPDZ1 K-Swap Megaphone Exhaust Header delivers aggressive performance gains and flawless fitment for your EG, EK, or DC2 chassis. Featuring a 4-1 Tri-Y long-tube layout and a tuned megaphone-style outlet, this header maximizes torque, throttle response, and high-RPM power – all while maintaining excellent ground clearance for lowered cars.

With a high-flow 2.5” 2-bolt collector, this version is perfect for builders who prefer a traditional flange connection while still demanding the airflow needed for naturally aspirated or lightly boosted K20/K24 builds.

Key Features:

• K-Swap Specific Fitment: Designed for K20 and K24 engines swapped into Civic EG, EK, and Integra DC2 chassis
• 4-1 Tri-Y Long Tube Design: Increases exhaust scavenging for torque and top-end horsepower
• 2.5” High-Flow 2-Bolt Collector: Smooth transition to midpipe for enhanced flow and compatibility
• Megaphone Outlet: Amplifies exhaust velocity for raw sound and serious performance
• CNC-Machined 3/8” Flanges: Ensures perfect seal and durability under extreme heat
• Offset Primary Design: Provides better ground clearance for slammed or track-prepped builds
• Ported Primary Flanges: Minimizes restriction for optimal exhaust gas flow
• Complete Kit: Includes header gasket, donut gasket, and connecting springs for an easy installation
