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

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

Part Number: 11981

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

This True Dual 2.5-inch Axle-Back system enhances the aggressive character of the naturally aspirated Lexus 5.0L V8 while maintaining refined daily drivability. Featuring Borla’s signature S-Type sound profile, premium T-304 stainless steel construction, and dual 4-inch bright chrome tips, this system delivers performance, durability, and a sophisticated motorsport tone without interior drone.


Designed for the Lexus RC F and IS 500 5.0L V8

This Borla exhaust system is engineered specifically for:

Lexus RC F 5.0L RWD Coupe

2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025

Lexus IS 500 5.0L RWD Sedan

2022, 2023, 2024, 2025

Whether you drive an early-production RC F or a new IS 500 F Sport Performance, this axle-back system integrates seamlessly with factory exhaust mounting points for precise OEM-level fitment.


True Dual 2.5-Inch Exhaust Design

The Borla 11981 features a True Dual 2.5-inch configuration, allowing each cylinder bank of the Lexus 5.0L V8 to flow independently. This balanced layout improves exhaust scavenging and increases exhaust velocity, contributing to improved throttle response and a more engaging driving experience.

Borla’s patented straight-through and multi-core muffler technology reduces restriction without compromising acoustic refinement. The result is improved performance characteristics while maintaining controlled sound output.


S-Type Sound Profile – Performance Without Drone

The S-Type sound level is engineered for enthusiasts who want a deeper, more aggressive exhaust tone while preserving daily comfort.

Sound characteristics include:

  • Deep and authoritative idle
  • Aggressive growl under acceleration
  • Clean high-RPM tone
  • No interior drone at cruising speeds

This makes the Borla S-Type Axle-Back ideal for daily-driven RC F and IS 500 owners seeking a refined but performance-oriented sound upgrade.


Premium T-304 Stainless Steel Construction

Borla manufactures this exhaust system using aircraft-grade T-304 stainless steel, which provides superior corrosion resistance and long-term durability compared to T-400 series stainless steel (such as 409).

Key construction advantages include:

  • Ultra-smooth mandrel bends for maximum exhaust flow
  • Precision CNC manufacturing for exact fitment
  • High-quality welds for strength and longevity

This ensures long-term performance in all driving conditions, from daily commuting to spirited canyon runs.


Dual 4-Inch Bright Chrome Exhaust Tips

This configuration includes dual 4-inch round bright chrome tips on each muffler assembly, constructed from T-304 stainless steel for durability and long-lasting shine. The polished chrome finish complements both factory and modified RC F and IS 500 rear styling.

For customers preferring a darker aesthetic, a black chrome tip version (Part #11981BC) is also available.


Optional Mid-Section Upgrade – Convert to Full Cat-Back™

For enthusiasts seeking increased sound volume and additional 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 system into a complete Borla Cat-Back™ exhaust system.

Important installation notes:

  • Mid-Sections 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 inlet pipes to the rear of the catalytic converters is required.
  • The Borla mid-section includes a Merge X-Pipe, increasing overall exhaust volume while maintaining the S-Type tone.

This modular design allows staged upgrades while ensuring system compatibility.
