Subie Speed Shop : Performance Parts and Upgrades for Subaru Vehicles

The first upgrade to any Subaru needs to be a cold air intake system. This allows the engine to breath exponentially better than the restrictive baffled air box. Colder denser air equals more power, better throttle response, and improved mpg. We carry Subaru cold air intakes from top brands including Cobb Tuning, Agency Power, Advanced Flow Engineering, AEM, Injen, Takeda and more.

After you have added a cold air intake the next step to making bolt on power with the Subaru is the exhaust system. A high flow performance cat back exhaust is going to free up exhaust flow by reducing back pressure and allow that turbo to spool quicker. The cat back exhaust will replace the mid section pipe and axle back portion of the factory exhaust system. A significant power increase can be expected with any 3" aftermarket cat back system on the and STI. Popular Subaru exhaust systems brands include Cobb Tuning, Megan Racing, Injen, Invidia, Tanabe, Magnaflow, CNT Racing, DC Sports, Borla, Greddy, Agency Power, and ARK Performance.

The turbo down pipe is another high reward upgrade for the turbocharged Subaru and STI. The down pipe connects the turbocharger to the factory cat back exhaust. To achieve the ultimate in exhaust performance a high flow down pipe is a necessity!
