The Injen Performance Cat-Back Exhaust System for the 2015-2021 Subaru WRX and WRX STI was designed from the ground up to compliment the aggressive styling and blistering performance of these sporty sedans. Our custom dual muffler design hones the tone of the engine into an ear-pleasing symphony. Purposefully delivering a crisp, clean, deep rumble at idle and an aggressive roar when you’re pushing the limits. Manufactured from only the highest grade 304 stainless-steel, from the flanges to quad titanium look tips, for the highest level of tensile strength and rust resistance. The premium polished finish on the mufflers is sure to impress anyone curious enough to peek at the undercarriage and the burnt titanium look exhaust tips offer superb aesthetics that perfectly compliment the sound of the system itself.
We design every performance product with ease of installation in mind. On the SES1207TT we’ve included V-Band clamps and flanges for the simplest, quickest installation possible. No need for any cutting, drilling, or modification of the vehicle to complete installation. The system uses all factory mounting points for simple and convenient placement and compatibility. To increase performance, we opted for a stepped piping design that keeps the flow rate consistent throughout the length of the exhaust. Keeping the flow rate consistent not only adds performance but also helps keep the tone of the exhaust where we designed it to be throughout the rev range.
An aftermarket exhaust system is one of the simplest modifications you can make to your vehicle that will add both power and personality to your ride. We make choosing an exhaust system easy with our superior build quality, tone, and performance. All protected by the world renowned Injen Limited Lifetime Warranty.
