Description

The HKS Super Turbo Muffler is a sophisticated, large-capacity exhaust system engineered to deliver an exceptional balance of low exhaust pressure, quiet daily operation, and powerful high-RPM performance for the DBA-R35 GT-R. Featuring a unique dual-diameter, quad-tip design and a straight-through internal structure, it reduces restriction for improved power potential while maintaining remarkably low noise levels at idle and cruising. This system is the intelligent choice for owners seeking significant flow improvements and a deep, authoritative exhaust note without excessive volume.

Product Overview & Purpose

This system addresses the need for a high-output exhaust that remains street-practical. It replaces the factory muffler with a larger, more efficient design that prioritizes flow with a straight-through path, housed within a large silencer for sound control. The result is a substantial reduction in backpressure—key for tuned applications—coupled with a refined, powerful sound character that is quiet when you need it to be and explosive when you demand it.

Product Highlights

🌬️ Optimized Straight-Through Flow for High Power
Engineered for step-up tuning, the internal design is a completely straight, unrestricted flow path. The piping progresses from a large Φ101.6mm intermediate pipe to a true quad-exit setup (Φ70mm x 2 → Φ60mm x 4), dramatically reducing exhaust backpressure to support significant horsepower increases, especially in modified vehicles.

🎵 Dual-Personality Sound Character

• Quiet & Civilized: Maintains a remarkably low noise level at idle and during normal driving, with a certified near-field exhaust noise lower than stock (87dB vs. 92dB). This ensures comfort and compliance for daily use.

• Powerful & Punchy Under Load: When the throttle is opened, the system unleashes a deep, sporty, and powerful exhaust note that embodies the GT-R’s performance character, providing thrilling auditory feedback during spirited driving.

✨ Distinctive Dual-Diameter Quad-Tip Design
Features a visually striking rear view with four tailpipes using two different diameters (124mm outer, 110mm inner). This layered, concentric design creates a bold, technical, and impactful appearance that emphasizes the car’s wide stance and performance intent.

🔧 Large-Capacity Silencer for Performance & Refinement
The key to its dual nature is the large-volume main silencer. It provides sufficient internal space to effectively dampen sound waves for quiet operation while allowing the straight-through design to minimize flow restriction—achieving both “high quietness and high output.”

Performance Philosophy

• Goal: To provide a massive improvement in exhaust flow capability for tuned performance, while retaining—and even improving upon—the daily drivability and noise compliance of the stock system. The focus is on unlocking power potential without compromising refinement.

• Focus: The ideal high-performance street exhaust for the modified GT-R. It is designed for owners who are tuning their vehicles for more power and need an exhaust that can handle increased flow, but who also value a quiet cabin during normal operation and a sophisticated, powerful sound under acceleration.

Installation & Usage Notes

• 🔧 Professional Installation Recommended
  Installation involves removing the factory rear exhaust section. Professional installation is recommended to ensure proper alignment, sealing, and secure mounting of the substantial system.
