The review
This is the one product in the batch where the legal fine print matters more than the spec sheet: it's certified for federal EPA emissions compliance only, which means it's explicitly illegal to sell, install or use in California, Colorado, New York or Maine — check your state before adding this to a comparator shortlist.
On the spec side, it uses a genuine 400-cell ceramic substrate with precious-metal coating (platinum, rhodium, palladium) rather than a cheap flow-through pipe, and it passed the EPA's required 40,000km road-durability test. The 5-year structural warranty plus a separate 2.5-year/40,000km emissions-performance warranty are both longer than typical for this category. Professional installation is recommended over a DIY swap.
Pros
- Passed the EPA's 40,000km durability road test
- 5-year structural warranty, 2.5-year emissions-performance warranty
- Precious-metal (Pt/Rh/Pd) coated ceramic substrate, not a cheap flow-through
Cons
- Federal-emissions-only — illegal to sell, install or use in CA, CO, NY and ME
- Professional installation recommended, not a simple DIY bolt-on
- Lowest rating (4.0 stars) and smallest review base (68) of the parts added this batch
Ideal for: Civic 2012-2013 / ILX 2013-2014 owners outside CARB states replacing a failed or stolen catalytic converter.
