Borla 11939 ATAK Axle-Back Exhaust System - Stainless Steel

The Borla 11939 ATAK (Acoustically Tuned Applied Kinetics) Axle-Back Exhaust System delivers the most aggressive sound level in Borla's street-legal lineup, engineered specifically for Mustang convertible applications. This performance exhaust system replaces the factory rear muffler and exhaust pipes, unleashing hidden horsepower while providing the distinctive Borla Sound of Power.

Key Features:

• ATAK technology delivers the highest available decibel levels, tuned like a graphic equalizer for optimum high-volume output without sound quality loss
• Constructed from premium T-304 stainless steel with ultra-smooth mandrel bends for maximum flow and durability
• 2.25-inch diameter tubing with split rear exit configuration
• Four 4-inch bright chrome rolled angle-cut tips for aggressive styling
• Multi-core technology designed to increase exhaust velocity, adding power and improving fuel economy
• Precision CNC manufacturing ensures accurate fit using factory hangers and rubber isolators
• Backed by Borla's Million-Mile Warranty

This axle-back system is designed for convertible models only and is not compatible with vehicles equipped with Active Valve Exhaust systems. Installation typically requires cutting the factory exhaust system and can be completed with basic hand tools and a reciprocating saw or pipe cutter. The ATAK sound level is calibrated specifically for high-performance enthusiasts who prefer exhaust note over stereo sound, delivering an intoxicating concert of steel, gears, and combustion.
