The 6.4L Hemi under the hood of a Grand Cherokee SRT deserves an exhaust note that matches its output, and the Borla 140633 ATAK Cat-Back Exhaust delivers exactly that. Built around Borla's patented Acoustically Tuned Applied Kinetics technology, this system produces the most aggressive tone in Borla's catalog while eliminating the drone that plagues so many aftermarket exhausts at highway cruising speed. Every piece is handcrafted from T-304 stainless steel in the USA, and the system bolts on without cutting, welding, or giving up your factory catalytic converters.
