Description Extended Information Post A Question
HKS released the Metal Catalyzer for Honda CR-Z making it the only catted header/downpipes available for the ZF1/ZF2. The CR-Z comes with an unconventional system that cuts out a traditional exhaust manifold, instead the down-pipe connects directly to the engine creating a 4-1 system. The HKS Metal catalyzer comes with a divided bell-mouth down-pipe creating the simulation of a 4-2-1 exhaust manifold. This then connects to a down-pipe which uses a high flow catalyzer.

Overall performance is improved with the largest change going from 4000 RPM onword. Pair this with a high flow exhaust and forced induction and you can expect even more results.

  • Honda CR-Z [ZF1] (2011, 2012)
  • Honda CR-Z [ZF2] (2013, 2014, 2015)
**Comes with EGR but has not been tested on 2013 onward due to lack of engine management**
  • 4-2-1 Bell-mouth Header for improved mid range performance
  • 51mm diameter piping (up from 42mm) for increased air flow
  • Removes the first catalyzer
  • Keeps EGR
