BULL BOOST PERFORMANCE K Series FG2 FA5 T3 Turbo Manifold for 2006–2011 Honda Civic Si K20 K24 K Swap

Part Number: 723098228285

The Bull Boost Performance K-Series Ramhorn T3 Turbo Manifold is engineered for high-horsepower K20 and K24 turbocharged applications requiring excellent spool response, strong midrange power, and reliable high-RPM performance. Designed specifically for the 2006–2011 Honda Civic Si FG2 and FA5 chassis, this manifold is also ideal for custom K-swap turbo builds demanding a durable and efficient bottom-mount turbo setup.

The ramhorn-style runner design helps promote fast turbo spool characteristics while maintaining strong exhaust flow efficiency throughout the powerband. Built from heavy-duty 304 stainless steel schedule 40 piping, this manifold is designed to handle extreme heat and boost pressures commonly found in competitive racing and high-performance street applications.

Each manifold features a fully ported low-angle merge collector to improve exhaust gas velocity and turbocharger efficiency. Precision TIG welding, CNC-machined flanges, and a thick one-piece construction ensure durability, sealing reliability, and long-term structural integrity under demanding conditions.

This manifold is ideal for autocross, drag racing, road racing, and high-performance street builds where quick spool and substantial power gains are critical.
