Aggressive Exhaust Upgrade. The Borla ATAK Dual Exhaust System with Chrome Tips is designed to deliver unmatched sound and performance for your Sierra. Featuring Borla's ATAK® muffler technology, it produces an aggressive exhaust tone with zero drone, while the included Polyphonic Harmonizer further enhances the deep, full-bodied sound. Built as a cat-back dual system, it improves exhaust flow for noticeable horsepower and torque gains.
Construction and Appearance. Crafted from premium T-304 austenitic stainless steel, this system offers superior durability compared to conventional 409 stainless steel. The dual 3.5" x 3.28" bright chrome tips add a bold, polished look to the rear of your truck, while CNC mandrel-bent tubing ensures maximum flow and precise fitment. A valve simulator is included to prevent check engine lights when removing the factory valance tips.
Installation. Installation is moderately difficult, requiring the removal of the factory valance tips. The system is designed for a precise fit but may require professional tools or assistance to ensure proper alignment.
Warranty. This exhaust system is backed by Borla's Million-Mile Warranty, ensuring confidence and long-term reliability.
Application. This Borla ATAK Dual Exhaust System with Chrome Tips fits 2024-2026 6.2L Sierra 1500 w/ factory dual exhaust, excluding AT4X.
