Our Civic FN2 Type-R 4-2-1 Tubular Race Exhaust Manifold & Downpipe replaces the restrictive standard cast iron manifold and improves exhaust gas flow thanks to its stainless steel, CAD-designed construction. It also replaces the restrictive catalytic converter, resulting in much improved throttle response and dyno-proven power gains. Features: Constructed from T304 stainless steel 4-2-1 design (offers greater mid range gains than a 4-1 design) 60mm Bore Collector 45mm Branch Diameter TIG welded Improved throttle response and gas flow Please note: sold for off road and track use only (will not pass an MOT test when fitted).
