The aFe Takeda cat-back exhaust for Subaru WRX/STi (2015–2021 2.0/2.5L H4) replaces the factory back pipe with mandrel-bent 3" to 2.5" 304 stainless tubing and dual 4.5" black stainless tips. It uses factory-style flanges and hangers for direct bolt-on installation, a mitered merge collector to reduce turbulence, and full TIG welding for strength while producing a more aggressive exhaust note.
