Our Civic Type-R Race Manifold 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 with a decat downpipe, 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) 2.5" bore collector TIG welded Improved throttle response and gas flow Direct bolt-on on fitment to standard or aftermarket backpipe (centre section)
