Super Converters flow much better than stock catalytic converters because their flow area is 26% greater than OE. These mono shell stainless steel units flow extremely free (great for engines up to 455 ci), and their single tube design eliminates all the welds common to OE for leakproof operation and greater efficiency.

Note: These catalytic converters are no longer legal for sale in the state of California and will not be shipped to the state of California.
