Borla F-150 2021 5.0L 4dr CC SB EC STB Lariat/KR/Platinum/LTD 3/2.25 SRE Cat-Back ATAK CHR Tips

This Borla cat-back exhaust system starts with a 3-inch diameter pipe that splits into dual 2.25-inch pipes, specifically designed to improve the power and sound of your 2021-2025 Ford F-150 equipped with the 5.0L V8 engine. It replaces the factory single tailpipe with a split rear exit configuration, complete with single 4-inch round bright chrome on T-304 stainless steel tips on each side. This system is tuned for the aggressive ATAK sound level, which Borla achieves using their patented Polyphonic Harmonizer Technology. This technology uses pipes of varying diameters and lengths to create multiple exhaust notes that blend together for a clean, rich, and full-bodied sound without any unwanted drone.

Borla builds this system from premium T-304 austenitic stainless steel, which is stronger and more durable than T-400 series steels, ensuring long-lasting performance. The ultra-smooth mandrel bends are crucial for maximizing exhaust flow and power. Precision computer numerical control (CNC) manufacturing guarantees an accurate fit, making installation more straightforward. This system is designed as a bolt-on installation, meaning no welding is required. It's important to note that adapter 60556 is needed for Crew Cab models with a Standard Bed (6' 7") and a 157.2-inch wheelbase, and adapter 60564 is required for Extended Cab models with a Long Bed (8' 2") and a 164.1-inch wheelbase. This system is not compatible with the Tremor or Black Appearance Package F-150s.

The ATAK system is engineered to unleash hidden horsepower by increasing exhaust velocity, which can add to driving excitement. Borla backs this system with their Million Mile Warranty, reflecting their confidence in the product's durability and performance.
