Designed to deliver the perfect balance of refined luxury, enhanced performance, and commanding exhaust sound, this premium exhaust system unlocks the true character of the Defender while maintaining everyday comfort.

Whether tackling off-road trails, towing, or cruising on the highway, the Yonristic exhaust provides a more responsive and engaging driving experience without compromising the Defender's versatility.
Available in AISI T304 stainless steel or optional Ti-6Al-4V (Grade 5) titanium, this exhaust system combines premium craftsmanship with exceptional durability and significant weight reduction.
Optimized 3-Inch Performance Architecture
The Yonristic Cat-Back Exhaust is engineered around a constant 3-inch exhaust pathway that maximizes exhaust flow from the factory connection point to the rear outlets.
By reducing restriction throughout the system, the Defender's turbocharged inline-six engine benefits from:
- Improved exhaust gas evacuation
- Reduced backpressure
- Enhanced turbocharger efficiency
- Sharper throttle response
- Increased engine responsiveness
- Deeper, more refined exhaust tone
The result is stronger performance throughout the RPM range while preserving smooth daily drivability.
Intelligent Dual-Valve Exhaust Control
The integrated electronic valve system allows drivers to instantly adjust the exhaust character to suit any driving environment.
With the valves closed, the system delivers a refined, subdued exhaust note ideal for city driving, highway cruising, and long-distance travel.
Open the valves using the included remote control to unlock a significantly more aggressive exhaust tone, allowing the turbocharged inline-six to produce a deeper, sportier sound with enhanced presence and character.
