Description
Upgrade your Chevrolet Silverado 1500 with the Borla 140998 ATAK Catback Exhaust System, engineered specifically for 2024 and 2025 models excluding ZR2 and AT4X trims. Crafted from premium T-304 stainless steel, this system offers superior durability and performance, featuring ultra-smooth mandrel bends that maximize exhaust flow and horsepower. The 3.5-inch main pipes seamlessly transition into dual 2.75-inch tips, finished with bright chrome on each T-304 stainless steel tip, providing a sleek and aggressive look. This exhaust system is designed to replace the factory system, requiring removal of the factory valance tips, and includes an adapter (60706) for crew cab standard bed vehicles with a 157-inch wheelbase. It also incorporates a valve simulator that prevents check engine lights, ensuring a hassle-free installation and operation. The ATAK muffler utilizes Borla’s Polyphonic Harmonizer Technology, which employs patented pipes of varying diameters and lengths to produce a rich, full-bodied exhaust note with no drone inside the cabin. For a quieter “S-Type” sound, replace the Polyphonic Harmonizer with muffler part 60679. Each system is precision manufactured using CNC technology to ensure perfect fitment and optimal performance, ultimately increasing exhaust velocity, horsepower, fuel efficiency, and delivering Borla’s signature sound of power. Backed by a Million-Mile Warranty, this exhaust system offers long-lasting performance and an unbeatable driving experience for enthusiasts seeking enhanced sound and power from their Silverado or Sierra. Please note installation requires removal of factory valance tips, and systems with different tip finishes or configurations are also available to customize your look.
