Skunk2 Alpha Series Header for Honda D16 Engines

Skunk2 Alpha Series Header for Honda D16 Engines

Unlock the hidden power in your single-cam with the Skunk2 Alpha Series Header for Honda D16 engines—an R&D-driven upgrade born from the same technology that propels Skunk2’s professional road-race and drag cars. Engineered specifically for 1988-2000 Civics, 1988-1991 CRXs, 1993-1997 Del Sols, and Canadian-market Acura ELs, this 4-2-1 Tri-Y header turns every on-ramp into a showcase of crisp throttle response and fatter mid-range torque.

Why it hits harder than generic “stainless” headers:

• Equal-length, stepped primaries (1.5"→1.625") accelerate exhaust velocity, adding up to double-digit gains throughout the rev range on both VTEC and non-VTEC D-series mills.
• Race-bred 2.5" true-merged collector with a formed spike smooths flow into your cat-back, eliminating the turbulence that robs horsepower.
• TIG-welded 304 stainless steel laughs at road salt and track heat cycles, so welds stay beautiful and cracks stay nonexistent.
• Dual O2 bungs—one OEM-position, one aftermarket—simplify wideband installs or data logging.
• Generous ground clearance means lowered Hondas stay scrape-free.
• Perfect fit with Kraftwerks D-Series Supercharger Kit or any stock-location turbo down the road.

Track-day only? Yes—the Alpha Series omits restrictive factory cats for maximum flow, making it the go-to choice for racers who want affordable, dyno-proven performance without gambling on no-name parts.
