Product Description

The Borla 11844 S-Type Axle-Back Exhaust System is a performance upgrade engineered specifically for 2013-2015 Cadillac ATS sedans equipped with the 2.0L inline-4 engine and rear-wheel drive. This S-Type exhaust delivers a richer, more aggressive exhaust note than the factory system while maintaining daily drivability with minimal unwanted drone. Constructed from premium T-304 stainless steel with smooth mandrel-bent tubing and straight-through, multi-core muffler design, the system enhances exhaust flow to improve throttle response and overall performance. The polished single split rear exit with 4" rolled angle-cut tips also adds a motorsport-inspired rear aesthetic.

Installation is straightforward with a direct bolt-on design that uses factory mounting points, and all necessary hardware is included. Note that for 2014-2015 ATS models, this system requires a vehicle equipped with a dual-inlet muffler to ensure correct fitment. Backed by Borla's Million-Mile Warranty, the 11844 S-Type Axle-Back Exhaust is ideal for Cadillac ATS owners who want enhanced sound, improved exhaust efficiency, and long-term durability over the stock exhaust system.
