Mishimoto Stainless Steel Cat Back Exhaust - 2015-2021 Subaru WRX/STI PDM_air-oil-separators

Mishimoto Stainless Steel Cat Back Exhaust - 2015-2021 Subaru WRX/STI PDM_air-oil-separatorsThe engineers at Mishimoto designed this cat back as a four piece design with precision TIG welded 304 Stainless Steel. This allows a smooth exhaust flow from the 3. 0" 2 bolt exhaust flange all the way through the 2. 25" y section. To top it off, this cat back includes two 2. 25" V Band clamps, a 3" exhaust band clamp, a new 3" 2 bolt flange gasket, and all stainless steel hardware, so you dont have to worry about your hardware rusting ever again!
