MagnaFlow 49986 is an OEM Grade Federal/EPA compliant direct-fit catalytic converter that replaces the front exhaust pipe and converter assembly sitting downstream of the 1MZ-FE manifold converters. Two 2.0 in flanged inlets collect both cylinder banks into a single 2.375 in flanged outlet across 36.75 in overall length, around a 6.625 in ceramic substrate converter body. It carries no oxygen sensor ports, because the sensors stay at the manifold converters upstream. Tubing is 16 gauge 409 stainless steel with 308 stainless MIG welds and 410 stainless barbed hangers, and two flat ring gaskets plus a donut gasket are supplied. This is a Federal/EPA 49-state part and is not CARB certified.
