GrimmSpeed - Subar 11-14 WRX / 08-14 STI - Non-Resonated Catback Exhaust System

Specially designed for the utmost sport-oriented driver, the GrimmSpeed engineered Non-resonated Cat-back Exhaust System guarantees maximum power, increased torque, and reduce backpressure.

The considerable reduction in back pressure ensures a noticeable increase in torque and power, enabling the engine to rev more freely than before.

Sometimes, this explanation is long and technical, especially where performance is concerned. This time, it's simple. The GrimmSpeed engineering and manufacturing teams are known for designing and producing products that use high-quality materials, offer perfect fitment, and have superior craftsmanship.

These catbacks are no different. If you're tired of your catback rattling against heat shields, tips hanging too low, being crooked or uneven, exhausts that are too loud, drone on the highway, or materials that are rusting or failing, then we have the solution for you. Beyond the product, the GrimmSpeed customer service team is ready to help you with any questions or concerns you might have along the way.

We stand behind our products 100% and our goal is to offer you a customer experience that makes you want to stand behind them as well.
