MagnaFlow's California Grade converter replaces the front Y collector converter assembly with a CARB compliant direct-fit unit that bolts in without cutting or welding. Two 2 in flange inlets gather both banks into a single 2.375 in outlet, and the spun round body uses 16 gauge 409 stainless steel tubing with 308 stainless steel MIG welds over a ceramic substrate. Overall length is 36.75 in. Two flat ring gaskets, a donut gasket, and outlet mounting hardware are included, and CARB Executive Order D-193-176 makes it legal for installation in all 50 states.
