The Circuit Werks Titanium Mufflered Axle-Back Exhaust System is designed for the 2008–2014 Lexus IS F, combining lightweight titanium construction with a performance-oriented exhaust sound for the naturally aspirated 5.0L V8. The system includes the Y-pipe and rear muffler sections while retaining the distinctive factory exhaust tips integrated into the IS F rear bumper.

Weighing approximately 13 lbs according to Circuit Werks, the system uses a 70mm Y-pipe that transitions into dual 50mm muffler sections. The muffler construction and exhaust layout are designed to provide a deeper, sportier V8 exhaust character that remains more subtle during normal driving and becomes increasingly pronounced under acceleration.

Titanium Construction: Constructed from titanium for a lightweight, performance-oriented alternative to a conventional exhaust system.

Approximately 13 lbs: Circuit Werks lists the complete axle-back system at approximately 13 lbs.

Complete Axle-Back System: Includes the Y-pipe and rear muffler sections required to replace the compatible factory rear exhaust components.

70mm Y-Pipe: Uses a 70mm main Y-pipe before transitioning into the dual rear exhaust sections.

Dual 50mm Muffler Sections: The Y-pipe splits into dual 50mm sections leading to the rear mufflers.

Mufflered Design: Uses rear mufflers to shape and control the exhaust note while providing a sportier sound than the factory exhaust system.

Retains Factory Exhaust Tips: Designed to work with the original Lexus IS F exhaust tips integrated into the rear bumper, maintaining the vehicle's distinctive factory rear appearance.

Sportier V8 Sound: Designed to give the naturally aspirated IS F V8 a deeper and more engaging exhaust character during startup, acceleration, and spirited driving.

Sound-Controlled Design: Circuit Werks uses muffler construction, exhaust pipe dimensions, and overall system layout to tune the sound characteristics of the exhaust.
