The ASTEK system for the BMW M4 is designed to improve engine performance through advanced exhaust gas flow optimization. This performance exhaust system reduces backpressure and increases overall system efficiency.
The downpipe and central exhaust configuration improves engine progression, especially at medium-high revs, offering a more immediate and linear response. The system is designed to maintain a balance between performance and drivability.
The active valve allows for dynamic sound management, with the possibility of customised configurations to suit the customer's driving style and preferences.
Made of 304/310 stainless steel , it guarantees thermal resistance, durability and high construction quality.
With ASTEK , the BMW M4 reaches a new level of efficiency and driving involvement.

Astek Exhaust BMW M4
Technical specifications: Available materials: 304/310 stainless steel, titanium, or Inconel upon request. Geometry, diameters, and volumes are sized based on the engine and vehicle architecture. Active valve integration or dedicated configurations are possible.
Custom design based on fluid dynamics calculations to optimize backpressure, gas velocity, and thermal stability. Each component is manufactured in-house with strict control over tolerances, fits, and finishes. TIG welding with internal shielding to preserve flow quality.
Maintenance: Periodically check the fasteners and system condition. For titanium, use non-aggressive detergents and avoid surface contamination.
