Would 304 stainless work, yes, but the temperatures on turbocharged cars can exceed the limits of 304 stainless enough to make them brittle and crack. 321 stainless steel has higher strength and toughness at elevated temperatures.

The short primaries and properly sized secondary’s also pull less heat from the exhaust gasses increasing turbine efficiency.

Invidia exhausts are among the most widely installed aftermarket systems on Subaru platforms globally — well-documented, well-supported, and proven across thousands of street and track builds.

Invidia exhausts are among the most widely installed aftermarket systems on Subaru platforms globally — well-documented, well-supported, and proven across thousands of street and track builds.
