Borla 140979BC Cat-Back Exhaust System for Ford Mustang EcoBoost

The Borla 140979BC Cat-Back exhaust system is engineered specifically for Ford Mustang EcoBoost models without the Active Exhaust feature. This performance exhaust delivers the signature Borla S-Type sound—aggressive when you want it, but completely drone-free inside the cabin for comfortable daily driving.

Key Features:

• 2.5-inch diameter mandrel-bent tubing for maximum exhaust flow
• S-Type sound level—perfectly balanced between touring and aggressive ATAK
• Dual 4-inch round black chrome tips on premium T-304 stainless steel
• Patented straight-through and multi-core muffler technology
• CNC-manufactured for precision fit with no modifications required
• Constructed from corrosion-resistant T-304 stainless steel throughout
• Increases horsepower, torque, and throttle response
• Improves exhaust velocity for better performance and fuel economy

Borla's straight-through design unleashes hidden horsepower by reducing backpressure and increasing exhaust velocity. Unlike inferior T-400 series stainless steel (such as 409), the premium T-304 construction resists corrosion and maintains its appearance for the life of your vehicle. Every Borla Cat-Back system is backed by their industry-leading Million-Mile Warranty, demonstrating the brand's confidence in their craftsmanship and materials.

This is a complete cat-back system that replaces everything from behind the catalytic converters to the rear bumper. Installation uses factory mounting points for a clean, professional fit.
