Weapon R R18 Race Header Description
This new Weapon R race header for the 2006+ Civic DX/LX/EX (R18 motor) replaces your undersized factory exhaust in favor of a full 2.5" exhaust setup. This Weapon R header is one of the largest on the market for the R18 Civic. It is made of 304 stainless steel and features CNC machine mandrel bending which clears the factory lower arm bars.

Key Features:
  • About a 6 whp gain, more with other modifications (see the official dyno results).
  • Stainless steel flanges.
  • Stainless steel CNC mandrel bent tubes.
  • TIG welded for strength and durability.
  • Eliminates catalytic converter for best performance.
  • One of the best power mods for the R18 Civic.
  • Comes complete with install hardware.
Emissions Notes: As with any race header, this product will eliminate your catalytic converter and is not smog legal. Your Civic may detect that your catalytic converter is missing and may throw a harmless Check Engine Light (CEL). If you want to get rid of this, you can just install an O2 Sensor CEL Eliminator.
