Tegiwa Exhaust Manifold 4-2-1 Decat Header - Civic Type R FN2

Our Civic FN2 Type R 4-2-1 Tubular Exhaust Manifold & Down pipe 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. New gaskets are included too.
