86-87 Grand National / T-Type Catco Performance Catalytic Converter
Since you have to use a catalytic converter anyhow, you might as well use one that will last a long time and will maintain your vehicle's performance level in the process. These direct fit catalytic converters not only outflow stock converters, but they also feature aluminized steel heat shields (many have dual shields), 409 stainless steel shells, 16-gauge stainless steel pipes and nipples, and a heat-resistant sealed mat, all of which help them last longer. These units are direct replacements for OE converters and will install with little or no modification. Some converters have steel air tubes with perforated holes to help distribute the airflow evenly, without robbing power. New flanges are included when necessary.
