Product Highlights

⚖️ Extreme Weight Reduction with Full Titanium
Constructed entirely from high-grade titanium, the SUPERIOR specR offers a dramatic reduction in unsprung and overall vehicle weight compared to the stock exhaust. This contributes directly to improved acceleration, braking, and handling responsiveness.

🎵 Powerful Yet Refined Titanium Sound Character
Titanium construction produces a distinctive, crisp, and metallic exhaust note that is both aggressive and refined. The system is engineered to enhance the VR38DETT’s sound without excessive drone, providing an exhilarating auditory experience that builds with RPM.

🌬️ Optimized Flow for High-RPM Performance
Designed to reduce exhaust backpressure, particularly in the high-RPM range, allowing the twin-turbo engine to breathe more freely. This can contribute to increased top-end power and improved turbo response, especially when paired with other bolt-on modifications.

✨ Aggressive Quad-Tip Aesthetic
Features a commanding quad-exit layout with large 124mm titanium tailpipes that fill the rear valance, giving the GT-R an unmistakable, race-ready presence from behind.
