BULL BOOST K-Series FG2/FA5 T3 Ramhorn Turbo Manifold (K20/K24 Bottom Mount – Civic Si / EG / EK)
Part Number: 723098228315

Unlock fast spool and serious power with the BULL BOOST Ramhorn Turbo Manifold, engineered for high-performance K-series builds that demand strong midrange torque and top-end power on platforms like Honda Civic Si and K-swapped EG/EK chassis.

This bottom mount ramhorn design is built to maximize exhaust efficiency and turbo response, helping large-frame turbos spool quickly while delivering consistent power all the way to redline. It’s an ideal solution for drag racing, road racing, and aggressive street builds.

Constructed from high-quality 304 stainless steel with thick schedule 40 piping, the BULL BOOST manifold is designed to handle extreme heat and high-boost conditions without compromise. The CNC-machined 1/2” thick flange ensures a strong, warp-resistant seal, while the one-piece construction increases durability and reliability.

A fully ported, low-angle merge collector improves exhaust flow and turbo efficiency, giving you better spool characteristics and overall horsepower gains. The integrated T3 flange supports a wide range of turbochargers, and the 44mm wastegate flange provides proper boost control for high-performance setups.

Professionally TIG welded and assembled, this manifold delivers the strength and precision required for serious builds pushing the limits.
