• 2015–2021 Subaru | WRX

Injen Performance cat-back exhaust system for the 2015-2021 Subaru WRX and WRX STI. Designed from the ground up to complement the aggressive styling and blistering performance of these sporty sedans, this system uses a custom dual-muffler design to deliver a crisp, clean, deep rumble at idle and an aggressive roar when you are pushing the limits. Manufactured from mandrel-bent 304 stainless steel - from the investment-cast flanges and V-band clamps to the quad burnt titanium look tips - with a show-quality polished muffler finish. A stepped 76mm-to-60mm piping design and investment-cast Y-pipe keep flow consistent through the rev range for dyno-proven gains of up to 13 horsepower and 11 lb-ft of torque. Installation requires no cutting, drilling, or modification, and all factory mounting points are used. Designed and manufactured in Pomona, California, and protected by the Injen Limited Lifetime Warranty.
