Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Performance Enhancement: Designed to boost engine efficiency and reduce backpressure with a 3'' stainless steel construction, delivering increased horsepower and torque for BMW X5M/X6M models.
  • Valved Sound Control: Features a Valvetronic Exhaust system with a valved catback design, allowing users to switch between sporty exhaust notes and quieter modes for different driving scenarios.

Key features

  • 1. Corrosion-Resistant SS304 Stainless Steel Construction

    • With a polished 1.5mm-thick SS304 stainless steel body, the CSZ Sport Exhaust ensures long-lasting durability and resistance to rust and corrosion, even in extreme driving conditions. This advanced material outperforms standard steel exhausts, which may degrade faster in harsh environments.*

  • 2. Valvetronic Exhaust System with Multi-Mode Control

    • The integrated valved catback design allows you to switch between performance and quiet exhaust modes via the Valvetronic system. This interactive feature adapts to driving scenarios, unlike fixed-exhaust systems that lack flexibility.*

  • 3. Optimized Flow Design for Enhanced Engine Performance

    • Engineered with a 3” diameter and optimized internal geometry, this exhaust reduces backpressure for improved throttle response and horsepower gains compared to OEM systems. The thicker steel construction also withstands high-temperature stress better than thinner alternatives.*

  • 4. Precision Fitment for BMW X5M/X6M Models

    • Designed specifically for the BMW X5M F85 and X6M F86, this exhaust guarantees a seamless OEM+ fit and maximizes performance for these high-output 4.4TT engines. It outperforms generic aftermarket exhausts that may compromise fitment or power delivery.*

  • 5. CE-Certified Safety and Compliance

    • With CE certification, the CSZ Sport Exhaust meets rigorous EU safety and emissions standards, ensuring reliability and legal compliance. This contrasts with uncertified products that may pose risks or fail regulatory checks.*
