The COBB EBCS for 2015+ WRX is a critical mod if you are going with an aftermarket J Pipe exhaust. The reason for this is because the factory boost controller is not designed to work with a free-flowing exhaust. When the J Pipe is changed out, there is much less backpressure on the turbocharger allowing it to spin more freely. This requires more precise adjustments to the wastegate (the control mechanism that is responsible for controlling boost. The COBB EBCS offer much better control over the wastegate and therefore boost. If you are going with a BCP E Tune, we will likely ask you to add the EBCS to your car if you already have a J Pipe on the stock EBCS.
