Overview

Borla ATAK Cat-Back Systems

Borla’s ATAK Cat-Back System 140776BC is designed for factory split rear exit vehicles ONLY (except ZR2 and AT4X models). This system features Borla’s aggressive ATAK muffler and Polyphonic Harmonizer Technology which utilizes patented units containing pipes of different diameters and lengths—to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound. T-304 stainless steel tips with a black chrome finish are included. (Using Borla Stainless Steel Polish P/N 21461 is NOT recommended with these black chrome tips. Borla suggests cleaning the tips with hot water and a microfiber cloth.)

Borla cat-back and axle-back exhaust systems blend patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive Borla Sound of Power respected by motoring enthusiasts everywhere. Each system is built from premium T-304 stainless steel to deliver the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow and power; and precision computer numerical control (CNC) manufacturing facilitates an accurate fit. Best of all, Borla stands behind every system—just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Additional notes:

* Add Adapter 60706 for Crew Cab with Standard Bed (6 ft. 7 in.) 157 in. wheelbase vehicles.
* Replace the Polyphonic Harmonizer behind the muffler in the ATAK system with muffler 60679 to attain the "S-Type" sound level (quieter than ATAK).
