Masarati MC20 / Cielo Exhaust System Race

Whenever you choose materials either Stainless steel or titanium or inconel the descriptions will change in following orders.

STAINLESS STEEL

Keller Performance Stainless Steel Exhaust System for  Maserati   MC20 / Cielo   2020+

The Keller Performance Stainless Steel Exhaust System delivers precision engineering, durability, and a balanced sound profile—making it an ideal solution for both daily driving and spirited performance use.

Designed using high-resolution 3D scanning and digital modeling, the system ensures perfect fitment, optimized exhaust flow, and reliable integration with factory mounting points. Each system is handcrafted in the United States from high-grade stainless steel, selected for its durability, thermal stability, and acoustic consistency.

Stainless steel offers excellent heat management and structural rigidity, allowing for stable exhaust flow and long-term reliability. Its slightly thicker wall characteristics compared to titanium and Inconel contribute to smooth pressure transitions and predictable sound behavior.

Sound Character

Stainless steel produces the deepest and most balanced tone of the three materials. The sound is rich, controlled, and refined—less sharp than titanium and less raw than Inconel. It delivers a full-bodied exhaust note with reduced rasp, making it ideal for drivers who want an aggressive presence without excessive harshness.

Valves, Resonators & Sound Control

Stainless steel systems are available with valved operation, compatible with factory valve systems, Val control, or Keller Performance’s remote control, offering convenient sound adjustment at the push of a button.

Resonators help eliminate drone and harsh frequencies, ensuring comfort during extended driving. For maximum daily usability, optional mufflers provide a quieter, more subtle exhaust note while retaining strong performance characteristics.

Why Stainless Steel

• Excellent durability and longevity
• Smooth, refined sound profile
• Ideal balance between performance and comfort
• Proven reliability for daily and performance use

This system is perfect for owners who want precision engineering, strong performance gains, and a refined yet commanding sound, all wrapped in a robust, long-lasting material.

TITANIUM

Keller Performance Titanium Exhaust System for  Maserati   MC20 / Cielo   2020+

The Keller Performance Titanium Exhaust System is engineered for those who demand exceptional performance, reduced mass, and a refined yet aggressive sound signature—without compromise.

Using full 3D scanning and advanced digital modeling, the system is designed to integrate seamlessly with the vehicle’s chassis and OEM mounting points while optimizing exhaust flow and maintaining consistent geometry throughout the system. Each unit is hand-fabricated in the United States using Grade-5 titanium, known for its extraordinary strength-to-weight ratio.

Titanium significantly reduces overall system weight compared to stainless steel, lowering rear-end mass and improving vehicle balance, responsiveness, and acceleration. Its excellent thermal properties allow exhaust gases to move efficiently while reducing heat soak in surrounding components.

Sound Character

Titanium delivers a high-energy, exotic tone—clean, sharp, and responsive. Compared to stainless steel, the sound is more pronounced and lively; compared to Inconel, it is slightly smoother and more refined. The result is a crisp, motorsport-inspired note with a premium, high-frequency edge, especially noticeable at higher RPM.

Valves, Resonators & Sound Control

Titanium systems are available in valved configurations, utilizing factory controls, Val control, or Keller Performance remote operation, allowing the driver to adjust sound and exhaust flow instantly for different driving conditions.

Resonators are used to control rasp and unwanted resonance, preserving sound clarity while maintaining performance. For customers seeking a more subtle exhaust note suitable for daily driving, optional mufflers provide additional sound reduction without compromising flow efficiency.

Why Titanium

• Significant weight reduction
• Faster throttle response and improved handling feel
• Exotic, high-end acoustic character
• Exceptional corrosion resistance and longevity

This system is ideal for drivers seeking maximum performance with a distinctly premium, modern sound, perfectly suited for high-end European supercars.

INCONEL

Keller Performance Inconel Exhaust System for  Maserati   MC20 / Cielo   2020+

The Keller Performance Inconel Exhaust System represents the highest level of exhaust engineering available, derived directly from aerospace and motorsport applications where extreme heat, pressure, and durability are non-negotiable.

Developed using high-resolution 3D scanning of the vehicle chassis and factory exhaust architecture, the system is engineered with millimeter-level accuracy to optimize exhaust gas velocity, minimize turbulence, and maintain perfect OEM-grade fitment. Every bend, transition, and collector is digitally modeled to ensure consistent flow behavior across all RPM ranges.

Constructed from Inconel 625, this system thrives where other materials reach their limits. Inconel retains structural integrity at temperatures exceeding 1,800°F, allowing exhaust gases to remain hotter and faster for longer distances. This results in maximum turbo efficiency, faster spool, reduced backpressure, and sustained performance during aggressive driving or track use.

Sound Character

Inconel produces the most raw, mechanical, motorsport-grade sound of all materials. The tone is sharp, metallic, and highly defined—crisp at high RPM with aggressive crackle and immediate throttle response. There is no artificial dampening or softness; what you hear is pure engine character, amplified with precision.

Valves, Resonators & Sound Control

Valved configurations are available using factory valve integration, Val control, or Keller Performance’s remote control system, allowing the exhaust to be opened or closed instantly at the press of a button.

Even on race-oriented Inconel systems, resonators are carefully integrated to eliminate unwanted frequencies such as rasp or harsh overtones without reducing performance. Resonators refine the sound, ensuring clarity and control while preserving the aggressive character Inconel is known for. Optional mufflers are available for customers who prefer a more restrained setup for street use, while still retaining the system’s performance advantages.

Why Inconel

• Ultimate heat resistance and longevity
• Maximum performance under extreme conditions
• Light weight compared to steel with superior strength
• Most aggressive, race-inspired sound profile

This is the no-compromise solution for drivers seeking the highest possible performance and the most visceral acoustic experience available in a street-legal exhaust system.
