This exhaust system is designed for factory split rear exit vehicles, excluding ZR2 and AT4X models. For Crew Cab with Standard Bed (6' 7") and 157" wheelbase, Adapter 60706 is required. The system features a 3.5" inlet into dual 2.75" outlets and uses an aggressive ATAK muffler with Polyphonic Harmonizer Technology, which utilizes patented units containing pipes of varying diameters and lengths to create multiple harmonized exhaust notes, delivering a clean, full-bodied sound without interior drone.

The Polyphonic Harmonizer behind the muffler in this ATAK system can be replaced with muffler 60679 to achieve the quieter "S-Type" sound level. This system includes dual 3.5" x 3.28" bright chrome tips made from T-304 stainless steel on each tail pipe. Installation requires removal of the factory valance tips. Systems with black chrome tips, carbon fiber tips, and versions that reuse the original equipment tips are also available.
