MagnaFlow 52329 is an OEM Grade direct-fit manifold catalytic converter for the passenger side bank, replacing the factory exhaust manifold and its close-coupled converter in one spun, one-piece assembly. High strength 16 gauge 409 stainless steel tubing and 308 stainless steel MIG welds resist corrosion, while a single laser fusion weld on the spun body reduces the chance of a leak. Mandrel bent tubing preserves the OE flow geometry so factory back pressure and fuel trims stay in range. One flange gasket, two bolts and one nut ship in the box, and installation needs no cutting or welding.
