S58 Valved Performance Catback Exhaust system - BMW S58 X3M F97 X4M F98 3.0T
The S58 Valved Performance Catback Exhaust System for the BMW S58 X3M F97 & X4M F98 3.0T is a high-performance upgrade designed to optimize both the sound and performance of your BMW’s S58 engine. With its innovative valved exhaust system, this system allows you to tailor the exhaust note to your preferences, providing a refined, quiet tone for everyday driving and a much more aggressive, race-inspired sound for spirited driving or track use. Additionally, it improves exhaust flow, reducing backpressure, and increasing horsepower, torque, and throttle response.
Key Features:
- Valved Exhaust System: The exhaust valves allow you to control the exhaust sound at the push of a button. Whether you want a more subdued and refined tone for daily driving or an aggressive, throaty growl for performance driving, the system provides flexibility and control over the sound.

This design leads to enhanced engine performance with improved airflow, delivering increased horsepower and torque while making your BMW X3M or X4M more responsive.
- Aggressive Exhaust Sound: When the valves are open, the system produces a deeper, more aggressive exhaust note that amplifies the growl of the S58 3.0T engine. When the valves are closed, the exhaust produces a quieter, more refined tone ideal for cruising or daily commutes.
- Increased Performance: The reduced backpressure and improved exhaust flow contribute to increased horsepower, torque, and acceleration, making your BMW X3M or X4M feel more responsive, dynamic, and powerful.
- Premium Stainless Steel Construction: Built from high-quality stainless steel, the exhaust system is resistant to corrosion and designed to withstand the high temperatures and wear from aggressive driving, ensuring durability and longevity.
