The Borla ATAK cat-back exhaust for the 2.4L turbocharged engine is a 3 in single exit T-304 stainless steel system built around Polyphonic Harmonizer technology, patented units with pipes of different diameters and lengths that blend multiple exhaust notes into a rich, full-bodied and aggressive ATAK sound with no drone in the cabin. The extended Polyphonic Harmonizer core exits inside a 4.5 in brushed T-304 stainless steel tip with a laser-cut Borla logo, on the rear passenger side. Laser-welded muffler end caps give a clean finish, and mandrel bends with CNC manufacturing ensure flow and an accurate fit.
