Subaru SS 3" Cat-Back Exhaust WRX 2015-2021, STI 2015-2021
California Residents: Prop 65 Warning
304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength. Four custom exhaust tips fill the factory bumper cut-outs perfectly, protruding just enough to show off the COBB logos etched into the top of each polished tip. Perfect fitment is achieved with either the Subaru factory downpipe or the COBB 3" SS Downpipe. The COBB 3" SS Cat-back Exhaust for the 2015+ Subaru WRX/STI is a triumph in design and execution. Install the COBB 3" SS Cat-back Exhaust on your WRX/STI and experience performance like no other.
