Borla S-Type Axle-Back Exhaust System – Black Chrome Tips

2015–2025 Lexus RC F 5.0L Coupe | 2022–2025 Lexus IS 500 5.0L Sedan

Part Number: 11981BC

Transform the sound and performance character of your Lexus V8 with the Borla S-Type Axle-Back Exhaust System (Black Chrome Tips) – Part #11981BC, engineered specifically for the 2015–2025 Lexus RC F 5.0L Coupe and 2022–2025 Lexus IS 500 5.0L Sedan.

Designed as a True Dual 2.5-inch Axle-Back system, this exhaust enhances the unmistakable tone of Lexus’ naturally aspirated 5.0L V8 while maintaining refined drivability with zero interior drone. Built from premium T-304 stainless steel and backed by Borla’s Million-Mile Warranty, this system delivers the performance, sound quality, and durability expected from one of the most respected names in performance exhaust.

  • 2017 Lexus RC F 5.0L RWD Coupe

Whether you are upgrading a launch-year 2015 RC F or a brand-new 2025 IS 500, this system is engineered for seamless integration and precise factory fitment.


True Dual 2.5-Inch Design for Maximum Flow

The Borla 11981BC features a True Dual 2.5-inch exhaust layout, allowing each bank of the 5.0L V8 to breathe independently. This configuration improves exhaust scavenging, enhances throttle response, and increases exhaust velocity.

Borla’s patented straight-through and multi-core muffler technology reduces restriction while maintaining refined sound control. The result is improved power delivery, sharper acceleration response, and the signature Borla Sound of Power.


S-Type Sound: Aggressive Yet Refined

The S-Type sound profile is engineered to deliver:

  • Deep, authoritative idle tone
  • Aggressive acceleration note under throttle
  • Clean, refined cruising sound
  • No interior drone

This makes it ideal for daily-driven RC F and IS 500 owners who want enhanced sound without sacrificing comfort.


Premium T-304 Stainless Steel Construction

Every Borla exhaust system is constructed from aircraft-quality T-304 austenitic stainless steel, offering superior corrosion resistance compared to common T-400 series stainless steel (such as 409).

Ultra-smooth mandrel bends ensure uninterrupted exhaust flow, while CNC precision manufacturing guarantees factory-level fitment.


Black Chrome 4-Inch Exhaust Tips

This configuration includes dual 4-inch round black chrome tips (two per muffler assembly), constructed from T-304 stainless steel for long-term durability and visual impact.

A bright chrome version is also available for those preferring a polished finish.


Optional Mid-Section Upgrade to Full Cat-Back™

For owners looking to further enhance sound and performance, Borla offers optional mid-section upgrades:

  • Mid-Section 60738 – For Lexus RC F
  • Mid-Section 60739 – For Lexus IS 500

Adding the appropriate mid-section converts this Axle-Back into a full Cat-Back™ exhaust system.

Important installation notes:

  • Mid-Section 60738 and 60739 are designed to work ONLY with Borla Axle-Back systems 11981 and 11981BC.
  • Installation requires cutting the factory mid-pipe behind the catalytic converters.
  • Welding of inlet pipes to the rear of the catalytic converters is required.
  • The Borla mid-section features a Merge X-Pipe, increasing overall exhaust volume while maintaining the S-Type tone.

This modular approach allows owners to upgrade in stages while maintaining system compatibility.
