Looking to replace the b/box on my WRX 03. Would like more noise when you put your foot down but do not want the constant drone of an overly loud exhaust as the car is my main transport (20k miles/year). Also would like a twin outlet exhaust similar to the standard look. Any recomendations ? Also will there be any power increase or other effects mpg etc.

 

We can make you a twin 2.5" exit exhaust that will give a nice deep noise when playing and quiet when cruising and still give good power gains .
