Product Description

The aFe 49-36801-P Takeda 304 Stainless Steel Cat-Back Exhaust System is a performance-oriented exhaust upgrade engineered for 2015-2021 Subaru WRX and WRX STI models with the 2.0L and 2.5L turbocharged engines. Constructed from mandrel-bent 304 stainless steel, this cat-back enhances exhaust flow and throttle response across the powerband. A mitered merge collector evenly distributes exhaust pulses, helping produce dyno-proven gains of up to +14 horsepower and +22 lb-ft of torque while delivering a deeper and more aggressive exhaust note compared to the factory system.

Featuring dual high-flow mufflers and quad polished 3.5" tips with laser-etched Takeda logos, the 49-36801-P system adds both performance and style to your WRX or WRX STI. The entire assembly is 100% TIG-welded for strength and corrosion resistance and installs with a direct bolt-on fitment using existing factory hangers and included hardware for a straightforward installation. Fitment is confirmed for 2015-2021 models; coverage beyond 2021 is unconfirmed at the time of this listing.
