CSZ Valved Sport Exhaust System for BMW F30 340i B58 3.0T 2014-2021 Stainless Steel Muffler Exhaust Pipe Valvetronic Fast Ship

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Performance Enhancement: Equipped with a valved system for adjustable exhaust sound and airflow, enabling seamless switching between sport mode (aggressive performance) and quiet mode (low-noise operation).
  • Durability & Heat Resistance: Constructed from 1.5mm thick stainless steel with mirror-polished and polished surfaces, ensuring corrosion protection and high-temperature stability for long-term use.

Key features

  • 1. Advanced Material Technology

    • With a 1.5mm thick stainless steel construction and mirror-polished surface, ensure long-lasting durability and corrosion resistance in harsh driving conditions. This exceeds the longevity of thinner, non-stainless steel exhaust systems commonly found in standard models*.

  • 2. Valvetronic Adaptive Design

    • With integrated valvetronic technology, adjust exhaust flow and sound output between aggressive performance modes and quieter daily driving scenarios, unlike fixed-valve systems that lack this versatility*.

  • 3. High-Performance Exhaust Flow

    • Deliver 20% faster exhaust gas evacuation compared to OEM systems*, enhancing engine responsiveness and power output while maintaining optimal backpressure for fuel efficiency.

  • 4. Dual-Use Scenario Optimization

    • Engineered for BMW F30 340i B58 engines, balance track-ready performance with refined sound levels for daily commutes, outperforming exhausts designed solely for racing or street use*.

  • 5. Comprehensive Compliance Standards

    • Meet stringent CE, FMVSS302, and EPR_Germany_Packing certifications, ensuring road legality, safety, and environmental compliance—unlike uncertified aftermarket alternatives*.
