Take your D-series build to the next level with the BULL BOOST Top Mount Turbo Manifold, designed for maximum turbo efficiency, aggressive power gains, and clean engine bay layout on Honda Civic setups.

This top-mount design positions the turbocharger higher in the engine bay, allowing for improved airflow, easier routing, and a more performance-focused layout—ideal for both street and high-horsepower builds.

Constructed from extra-thick 3mm seamless 304 stainless steel, the BULL BOOST manifold is built for durability under extreme heat and boost conditions. The reinforced flange design helps prevent warping, ensuring a reliable seal even in demanding applications.

The 4-1 merge collector is fully TIG welded and ported to maximize exhaust flow, helping improve spool time, horsepower, and overall engine efficiency. Designed to work with both T3 and T4 turbochargers, this manifold gives you flexibility when choosing your turbo setup.

A 44mm V-band wastegate flange is included for precise boost control, making it ideal for performance builds that require stable and consistent boost levels.
