Description
The Borla ATAK Cat-Back System 140776CF is designed for vehicles with a factory split-rear exit; it does not fit ZR2 or AT4X models. For Crew Cab vehicles with a 6 ft. 7 in. standard bed and 157 in. wheelbase, add Borla adapter 60706.
This single-in/dual-out cat-back system uses a 3.50-inch intermediate pipe and one ATAK turbo muffler with a single inlet and single outlet. Borla’s Polyphonic Harmonizer Technology uses pipes of different diameters and lengths to create multiple exhaust notes that combine into a clean, rich, full-bodied sound.
The system is made from natural-finish 304 stainless steel, with mandrel-bent tubing and CNC manufacturing. It includes hardware and four round, slant-cut carbon-fiber tips with bright centers, rolled edges and 3.50-inch outlets. Tailpipe diameter is 2.75 inches. Catalytic converters are not included.
