If you are looking to save a little money but still get most of the benefits of a cat back exhaust system, however, aluminized steel may be the way to go. Made from traditional steel that’s been coated on all sides with aluminum-silicon alloy, these systems are very strong thanks to the metallurgical bond which still provides a level of corrosion resistance. While the aluminum coating reflects heat well, the steel can corrode if the aluminum layer is chipped or scraped off. Most cat-back systems will come in either an aluminized or stainless steel version.
Most designs of the time therefore included secondary air injection, which injected air into the exhaust stream. This increased the available oxygen, allowing the catalyst to function as intended.
