Fitment

  • 2002-2006 Acura | RSX
  • 2002-2005 Honda | Civic Si

Description

The MagnaFlow HM Grade Federal/EPA compliant direct-fit catalytic converter for the 2002-2005 Honda Civic Si and 2002-2006 Acura RSX keeps the check engine light off with free-flowing mandrel-bent tubing and highly corrosion-resistant stainless steel construction. The spun body converter installs with no cutting or welding required, replicating the OE design with a single laser fusion weld that greatly reduces the possibility of a leak, while the compact low-mass design allows greater thermal efficiency.
