The main function of a catalytic converter is designed to reduce pollutants by causing carbon monoxide, unburned
hydrocarbons, and nitrous oxides to completely combust by converting them into safe carbon dioxide, water, and
nitrogen. The catalytic converter is the main source of air flow restriction in any exhaust system.The stock converter, especially on the Legend, is rather large and cumbersome, hindering exhaust flow and power just a tad. An aftermarket unit is much smaller but provides the same function. A catalytic converter should be checked after 100,000 miles or so to inspect for damage, cracks, or clogs which will reduce air flow even more and may have you failing the smog test. There are quite a few high performance catalytic converter companies out there. Car Sound, Perfection, and Random Technologies are a few. The Car Sound converter is a bit larger than Perfection's, so exhaust flow will be a bit more restrictive. Even though that means less free-flow, it also means less noise, which is what you want in most cases. Unfortunately no company has a direct bolt-on replacement for the Acura Legend, so you'll need to get the universal fit and have it custom installed. |
