The Gibson Performance Patriot Skull Series Exhaust is the complete opposite of what the company has typically done. Sonically, Gibson Performance Exhaust brings you a sound that’s more aggressive, powerful, and brings your engine to life. Aesthetically, the Patriot Skull is edgy, fresh, and has an attitude you can’t overlook.
The ATAK system is the most aggressive muffler section that BORLA produces for the E90/E92 M3. Acoustically Tuned Applied Kinetics allows for a very high volume without drone and distortion. BORLA manages the sound waves inside the exhaust to produce an exhaust note that maintains its tone as revs rise. With ATAK, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.
