Japspeed 4-2-1 Race Exhaust Manifold Decat - Honda Civic Type R FN2 (06-12)

The Japspeed 4-2-1 Tubular Race Exhaust Manifold and Downpipe is designed to improve exhaust gas flow, throttle response and engine performance on the Honda Civic FN2 2.0 Type R.

Manufactured from T304 stainless steel, this CAD-designed tubular manifold replaces the restrictive standard cast iron exhaust manifold and catalytic converter, allowing exhaust gases to flow more efficiently.

The 4-2-1 manifold configuration is designed to deliver improved mid-range performance compared with a traditional 4-1 design, making it particularly suitable for naturally aspirated performance applications.

Featuring 45mm diameter branches and a 60mm bore collector, the manifold is designed to optimise exhaust flow and reduce restrictions within the exhaust system.

TIG-welded construction provides strength and durability, while the improved exhaust flow helps deliver sharper throttle response and dyno-proven power gains.
