This 3.5" into dual 2.75" system is designed for factory split rear exit vehicles, except ZR2 and AT4X models. For Crew Cab with Standard Bed (6' 7") 157" Wheelbase vehicles, Adapter 60706 is required. The system features an aggressive ATAK muffler and Polyphonic Harmonizer Technology, utilizing patented units with pipes of varying diameters and lengths to create harmonized exhaust notes for a clean, rich sound without interior drone.

The Polyphonic Harmonizer behind the muffler in this ATAK system can be replaced with muffler 60679 to achieve the S-Type sound level, which is quieter than ATAK. Dual 3.5" round black chrome on T-304 stainless steel tips are featured on each tail pipe. Cleaning the black chrome tips should be done with hot water and a microfiber cloth, as stainless steel polish is not recommended. Installation requires removal of the factory valance tips.
