One thing that most people can agree on is the good old sound of a Subaru Flat 4 Turbo with a quality exhaust system. Some Subaru models now do not have the Iconic rumble, due to the fact that they use equal length headers. This 2015 WRX STI has Unequal length headers which keeps that old fashioned subie rumble. Adding an Agency Power Cat-Back intensifies this low deep tone. One of our employees had this exhaust set up installed on his car last week, along with a short shifter kit. The new noise with the cat-back exhaust is both intoxicating and exotic. You would not believe these sounds are coming from a 4 Door sedan. The overall quality, fit & finish and noise is one of this exhaust system is second to none. Listen to all the great noises and check out all of our Agency Power subaru parts.
