Product Description

The Borla 11981 S-Type Axle-Back Exhaust System is a premium exhaust upgrade engineered for high-performance Lexus models equipped with the naturally aspirated 5.0L V8. Specifically designed for 2015-2025 Lexus RC F coupes and 2022-2025 Lexus IS 500 sedans with rear-wheel drive, this system replaces the factory rear exhaust section behind the mufflers with a precision-engineered S-Type design that enhances exhaust flow and delivers a richer, more assertive exhaust note than stock with minimal unwanted drone.

Made from premium T-304 stainless steel with smooth mandrel bends and straight-through multi-core mufflers, the 11981 axle-back system improves exhaust efficiency while retaining durability and corrosion resistance. Dual 4" bright chrome round tips give a bold visual upgrade at the rear and integrate cleanly with the vehicle's OE rear valance. Installation is straightforward with a direct bolt-on fitment using factory hangers and included hardware - no cutting or welding required at the rear section. Designed to give your Lexus a refined yet aggressive sound, the 11981 is backed by Borla's Million-Mile Warranty, ensuring long-lasting performance and reliability for enthusiasts seeking both sound and quality enhancements.
