Japspeed 4-2-1 Race Exhaust Manifold Decat for Honda Civic Type R EP3 (01-06)

The Japspeed 4-2-1 Race Exhaust Manifold is designed to improve exhaust gas flow, throttle response and engine performance on the Honda Civic EP3 2.0 Type R (2000–2005).

Manufactured from T304 stainless steel, the manifold replaces the restrictive standard cast iron manifold with a CAD-designed tubular construction. It also incorporates a decat downpipe, replacing the factory catalytic converter to improve exhaust gas flow.

The 4-2-1 design is intended to provide greater mid-range power gains compared to a 4-1 manifold, making it a suitable upgrade for improving engine responsiveness and performance.

Featuring a 2.5" bore collector and TIG-welded construction, the manifold offers direct bolt-on fitment to either the standard or an aftermarket centre exhaust section.
