BMW M3 (G81 series) – Capristo Exhaust System

Technical Description:

The Capristo Exhaust System for BMW M3 (G81 series) is a high-performance exhaust solution crafted from stainless steel, specifically designed for the BMW M3 G81 model. This “cat back” system consists of various components for comprehensive performance and engine sound optimization, tailored to the unique characteristics of the BMW M3 G81.

1. High-Performance Catalytic Converters: The system is equipped with a pair of high-quality catalytic converters featuring 200 cells, engineered to effectively remove the particulate filter (FAP) while maintaining emissions compliance. These high-flow catalytic converters enhance exhaust gas flow, reducing restrictions and resulting in improved engine response and power gains.
2. Non-Silenced Center Section: The Capristo Exhaust System’s center section is engineered to maximize exhaust gas flow while minimizing power losses. This non-silenced component allows for an unleashed engine sound and overall power increase for the BMW M3 G81.
3. Rear Silencer with Controlled Valves: The rear silencer is equipped with electronically controlled valves, operable through the original BMW management system. These valves enable the driver to control the exhaust volume according to driving modes and preferences. In sport or track modes, the valves open fully, producing a deep and aggressive sound, while in comfort mode, they partially close for a more discreet sound level, tailored to the BMW M3 G81.
4. Anodized Aluminum Terminals with Carbon Fiber Coating: The system features high-quality anodized aluminum terminals, offering both an elegant appearance and corrosion resistance. These terminals are coated with carbon fiber, adding a touch of sportiness and refinement to the rear of the BMW M3 G81.

Design and Development:

The Capristo Exhaust System for BMW M3 G81 undergoes advanced engineering and meticulous development. Utilizing reverse engineering, precise laser scanning is performed on the original exhaust line of the BMW M3 G81. Based on this data, a CAD model is created to design and test initial prototypes, ensuring perfect fitment to the vehicle’s specifications and performance optimization without compromising reliability.

Enhanced Performance:

The Capristo Exhaust System delivers significant performance gains tailored to the BMW M3 G81:

• Sound Level Increase:
  • Stock Exhaust (valves open): 102 dbA
  • Capristo Exhaust (valves open): 126.7 dbA
• Power Increase:
  • Stock Exhaust: 519.7 hp at 6024 rpm
  • Capristo Exhaust: 532.3 hp at 6470 rpm
• Torque Increase:
  • Stock Exhaust: 693.4 Nm at 4186 rpm
  • Capristo Exhaust: 708.6 Nm at 4062 rpm Sound remains the same as stock at both volume and tone when valves are closed.
