The Borla 14-21 Toyota Tundra 4.6L/5.7L ATAK Cat Back Exhaust is a high-performance Cat-Back™ system designed to enhance power and sound. Featuring a 2.25" diameter True Dual design with split rear exits, it includes single 4" round bright chrome T-304 stainless steel tips on each tailpipe, with an option for black chrome tips. The system incorporates an internal H-Pipe within the muffler to boost performance and refine exhaust tone. Constructed from premium austenitic T-304 stainless steel, it offers superior durability and corrosion resistance compared to standard 409 stainless steel. Ultra-smooth mandrel bends and CNC manufacturing ensure optimal flow and precise fitment. This lightweight system outflows the factory exhaust, reduces weight, improves fuel economy, and delivers the aggressive ATAK® sound without interior drone. Borla backs this exhaust with a Million-Mile Warranty, reflecting its commitment to quality and performance.
