MagnaFlow 96-99 BMW M3 L6 3.2L / 96-98 328i/328is L6 2.8L California Catalytic Converter Direct Fit

E36 BMW owners running the inline-six know that finding a CARB compliant catalytic converter for these cars can be a challenge. MagnaFlow 4481664 covers the 1996-1999 M3 with the 3.2L S52 and the 1996-1998 328i and 328is with the 2.8L M52 -- all using the same direct-fit converter that interchanges with OE part 18 30 1 744 162.

Built from 16-gauge 409 stainless steel tubing with mandrel bends, this converter matches the factory exhaust path that MagnaFlow mapped using 3D scanning. The spun body uses a single laser fusion weld, and 308 stainless steel MIG welds handle the pipe joints. A stamped collector design helps maintain smooth exhaust flow through the converter. Two Torca AccuSeal exhaust clamps are included, each providing 360-degree evenly distributed clamping force to prevent pipe distortion.

No cutting or welding is needed -- the Torca clamps handle the connections. This is a meaningful advantage on E36 BMWs where access to the exhaust is tight and welding underneath would add complexity. This converter meets California Air Resource Board standards and is legal in all 50 states. Verify your vehicle's Executive Order number and Engine Family Number before installation.
