Borla S-Type Axle-Back Exhaust
2015–2023 Ford Mustang EcoBoost / V6 Convertible
Part #11938 • T-304 Stainless Steel • Made in USA • Million-Mile Warranty
The S-Type Difference
Borla’s S-Type exhaust sits in the sweet spot between their mild Touring and aggressive ATAK sound levels. It delivers a loud, powerful, throaty roar under acceleration while maintaining near-zero drone at highway cruising speeds. For the 2.3L EcoBoost, the S-Type brings out the turbocharged character with a deep, refined tone that belies the four-cylinder displacement. This is the exhaust for drivers who want to be heard without the compromise.
Premium Construction
Every component is crafted from aircraft-quality T-304 austenitic stainless steel for maximum durability and corrosion resistance. The mandrel-bent tubing ensures smooth, consistent internal diameter throughout every curve — no crimping, no restriction, no compromise. Borla’s patented straight-through multi-core muffler technology replaces the factory baffled design with a free-flowing core that reduces backpressure and liberates hidden horsepower and torque from your EcoBoost.

— Why we stock this
This is the Borla part our customers ask for most.
If you want the install done by experienced Mustang techs who run Borla daily, drop the car off in Thousand Oaks. Otherwise, this is a direct bolt-on with clear instructions and clamp reuse from your existing Borla Cat-Back system.
