The aFe Twisted Steel long-tube header in 304 stainless steel with catalytic converter for 2013–2019 Subaru Outback/Legacy (2.4–2.5L) uses mandrel-bent 1-5/8" to 2-1/2" tubing and formed collectors to improve exhaust velocity and pulse control. The included less-restrictive catalytic converter and factory-style flanges allow bolt-on installation in stock locations, while 100% TIG-welding ensures strength and durability.
