Tomei Expreme Ti Full Titanium Muffler Kit – 1999-2002 Nissan S14 SR20DET

The Tomei Expreme Ti Full Titanium Muffler Kit is Tomei's uncompromising answer to the demands of true competition exhaust engineering — a complete titanium exhaust system built for the Nissan S14 SR20DET, engineered from the highest-grade titanium materials available, and designed around a racing-inspired straight-as-possible routing layout for maximum exhaust flow efficiency. From the large-diameter main pipe to the high-flow silencer and titanium tip, every element of the Expreme Ti reflects Tomei's decades of motorsport development experience. The result is a system that delivers measurable weight savings, improved exhaust flow, and the unmistakable titanium sound character that defines serious SR20DET builds — without compromise.

Key Features:

• Full titanium construction — highest-grade titanium materials throughout the entire system, from the main pipe to the silencer and tip
• Racing layout design — straight-as-possible routing geometry for maximum exhaust flow efficiency and minimal back pressure
• High-flow silencer — large-diameter silencer engineered for high-flow performance while maintaining a competition-appropriate exhaust note
• Significant weight reduction — 9.85kg lighter than the equivalent steel exhaust system for the S14 platform
• Titanium tip — large-diameter titanium exhaust tip with titanium broad construction for a premium competition finish
• S14 SR20DET specific — engineered and validated for the Nissan S14 SR20DET application
• Tomei competition pedigree — developed by one of Japan's most respected motorsport engineering brands with decades of proven competition results

Performance Benefits:

• Weight Reduction: At 9.85kg lighter than the factory steel exhaust system, the Expreme Ti delivers meaningful unsprung and total vehicle weight reduction — improving power-to-weight ratio, acceleration, and handling balance. For a platform where every kilogram matters, this is one of the highest-impact weight reduction modifications available
• Exhaust Flow Efficiency: Tomei's racing-inspired straight-routing layout minimizes bends and restrictions in the exhaust path — reducing back pressure and improving exhaust scavenging efficiency across the RPM range. The result is improved throttle response and top-end power delivery on the SR20DET
• High-Flow Silencer: The Expreme Ti's large-diameter high-flow silencer is engineered to minimize restriction at the exhaust outlet — maintaining the flow gains of the straight-routing main pipe all the way through to the tip. Competition-level flow without sacrificing the system's structural integrity or longevity
• Titanium Sound Character: Full titanium construction produces the distinctive high-frequency titanium exhaust note that defines serious competition builds — a sharper, more focused sound character compared to steel systems, with a tone that reflects the SR20DET's high-revving nature
• Long-Term Durability: Titanium's exceptional corrosion resistance and strength-to-weight ratio ensure the Expreme Ti system maintains its performance and appearance over the long term — resisting the rust and degradation that affects steel exhaust systems in performance and track environments

What's Included:

• Tomei Expreme Ti full titanium muffler kit — TB6090-NS08B
• All required hardware for installation

Installation Notes:

• Professional installation strongly recommended — titanium exhaust systems require care during installation to avoid thread damage and ensure proper sealing
• Use anti-seize compound on all exhaust fasteners during installation
• Inspect all exhaust gaskets and replace as needed during installation
• Allow the system to heat cycle several times before checking all fastener torque
• Verify clearances throughout the exhaust routing before finalizing installation

Why Full Titanium?

Steel exhaust systems are adequate for stock and mildly modified applications — but for a serious SR20DET build, the weight, corrosion resistance, and sound character of a full titanium system represent a meaningful upgrade in every dimension. Titanium's exceptional strength-to-weight ratio allows Tomei to build a system that is simultaneously lighter, stronger, and more corrosion-resistant than any steel equivalent — while the material's acoustic properties produce the distinctive titanium exhaust note that defines competition-level builds. For an S14 build where performance, weight, and presentation all matter, the Expreme Ti is the definitive exhaust choice.

The Nissan S14 SR20DET Platform:

The Nissan S14 Silvia is one of the most celebrated Japanese sports cars of the 1990s — a lightweight, rear-wheel-drive platform powered by the SR20DET turbocharged inline-four, renowned for its tunability, balanced chassis dynamics, and motorsport pedigree across drifting, time attack, and circuit racing. The SR20DET's robust bottom end, responsive turbo architecture, and strong aftermarket support have made the S14 a perennial favourite for performance builds — with well-supported power levels from 300 to 500+ horsepower on the factory block. At these power levels, every gram of weight reduction and every improvement in exhaust flow efficiency contributes to the build's overall performance — making the Tomei Expreme Ti a natural choice for any serious S14 SR20DET build.

Why Tomei Powered?

Tomei Powered is one of Japan's most respected and longest-established motorsport engineering brands — with a product lineup spanning camshafts, valve train components, engine internals, exhaust systems, and fuel system components across the full spectrum of Japanese performance platforms. Tomei's engineering philosophy is rooted in genuine motorsport development — their products are validated in competition before reaching the aftermarket, ensuring that every Tomei component delivers the performance and reliability that serious builds demand. The Expreme Ti exhaust line represents Tomei's highest level of exhaust engineering — a competition-grade titanium system built without compromise for enthusiasts who demand the best.

Perfect For:

• S14 SR20DET builds targeting maximum weight reduction as part of a comprehensive performance build
• Time attack and circuit racing S14 builds where exhaust weight and flow efficiency directly impact lap times
• Drift builds where weight reduction and exhaust note character are both priorities
• Street builds where a premium titanium exhaust system is the finishing touch on a serious SR20DET build
• S14 owners who want a competition-proven exhaust system from one of Japan's most respected motorsport brands

Pro Tip: Pair the Expreme Ti with a Tomei or equivalent high-flow catalytic converter or test pipe for maximum exhaust system flow efficiency. The Expreme Ti's straight-routing design delivers its full benefit when the upstream exhaust path is equally unrestrictive — a matched front pipe and cat/test pipe combination will maximize the flow gains across the full exhaust system.

Note: Professional installation strongly recommended. Verify fitment for your specific S14 SR20DET application before ordering. Titanium exhaust systems require proper installation technique — consult an experienced performance exhaust installer.
