Product Information
This MagnaFlow California Grade converter is the front primary catalyst for BMW's 3.0L inline six, and it carries CARB Executive Order D-193-198, which makes it legal to install in California and other CARB states on the listed vehicles. The 19.25 in assembly runs 3 in inlet and outlet diameters into a round spun body, 5 in across and 9.625 in long, closed with a single laser fusion weld instead of a seam; the compact low-mass design also reaches light-off temperature faster. Tubing is high-strength 16 gauge 409 stainless steel with mandrel bends and 308 stainless steel MIG welds over a ceramic substrate, and two oxygen sensor ports sit pre-converter and midbed to match the factory sensor layout. Gaskets and corrosion-resistant 410 stainless steel hangers are included; clamps are not. MagnaFlow covers it with a 5 year limited construction and emissions warranty.
