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.
Features
- Constructed from T304 stainless steel
- 4-2-1 design (offers greater mid range gains than a 4-1 design)
- TIG welded
- Improved throttle response and gas flow
Please note: this is designed for off-road/motorsport use only. You will not pass a UK emissions test or police road side check with this installed on the vehicle.
