Emissions Standards
As ARH catalytic converters are designed primarily for the US market, they are not officially tested to Euro Emissions standards. However, ARH have tested a large variety of catalytic converters. Through their own testing, with local garages and test laborities, ARH have established their catalytic converters perform equally as well as the Euro Type Approved catalytic converter equivalents.
Please note. These are Non-Type approved catalytic converters. It is therefore, “ILLEGAL TO SUPPLY THESE PARTS FOR TYPE-APPROVED VEHICLES FIRST USED ON OR AFTER 1ST MARCH 2001.”
American Racing Headers is the leader in high quality and high-performance header and exhaust systems. Made entirely in the USA with US sourced materials, you can rest assured knowing that ARH quality comes second to none.
Attention to detail drives every stage of their process, from prototyping to production. ARH exhaust systems have been race proven time and time again with championships to show it!
The manufacturers catalytic converter warranty covers the construction of the catalytic converter, and does not cover against emissions testing. Vehicles running healthily that are not running too lean or rich should pass an emissions test with ARH catalytic converters installed without issue, but this is not a guarantee. The warranty covers failure of the catalytic converter. Should the catalytic converter fail, please contact us to discuss your options.
