A California Grade CARB compliant direct-fit converter carrying CARB EO number D-193-184, which makes it legal to sell and install in California, New York, Colorado and Maine as well as the federal states. The body is spun from 16 gauge 409 stainless with 308 stainless MIG welds and a ceramic substrate, and a single laser fusion weld replicates the OE spun-body design to cut leak paths. Overall length is 30.625 in with four oxygen sensor ports and a flanged inlet. Mandrel-bent tubing preserves the factory exhaust geometry, and it bolts in with no cutting or welding.
