This system is designed for factory split rear exit vehicles, except ZR2 and AT4X models. For Crew Cab with Standard Bed (6' 7") and 157" wheelbase vehicles, Adapter 60706 must be added. The 3.5" into dual 2.75" system delivers the classic S-Type sound level with no interior drone.

The small muffler behind the primary muffler in this S-Type system can be replaced with Polyphonic Harmonizer 60680 to achieve the ATAK sound level, which is louder than S-Type. An optional True Dual Cat-Back system is also available. This system features dual 3.5" round black chrome on T-304 stainless steel tips on each tail pipe. Installation requires removal of the factory valance tips.

Do not use stainless steel polish p# 21499 with black chrome tips clean the tips with hot water and a microfiber cloth. Systems with bright chrome tips, carbon fiber tips, and systems that reuse the original equipment tips are also available. Cat-Back and Axle-Back exhaust systems feature patented straight-through and multi-core technology for increased exhaust velocity, power, and fuel economy, along with the distinctive sound. Each system is constructed from premium T-304 stainless steel for performance and durability, with ultra-smooth mandrel bends and CNC manufacturing for precise fitment.
