The Borla ATAK axle-back system replaces the factory mufflers and rear piping with 2.75 in mandrel-bent T-304 stainless tubing and two race-inspired ATAK mufflers, delivering Borla's most aggressive sound level. Acoustically-Tuned Applied Kinetics tuning shapes the muffler cores for a hard exterior tone while keeping the cabin free of harsh resonance. It finishes in a pair of 4.5 in polished stainless round rolled, angle-cut tips and installs as a direct bolt-on using factory hardware.
