This Borla ATAK cat-back runs a 3 in true dual layout with a Merge X-Pipe and retains active valves so the factory active-exhaust modes keep working. Its mufflers use Borla's Polyphonic Harmonizer technology, blending pipes of varying diameter and length into a full, layered note, and the ATAK sound level delivers Borla's most aggressive tone without cabin drone. It exits through 4 in black chrome on T-304 stainless tips.
