Valvetronic Designs presents a true performance enhancement for BMW X3M and X4M owners seeking an unrivaled exhaust experience. Engineered specifically for the S58 engine, this system elevates both the sound and driving performance of your BMW, creating a thrilling, emotional driving experience that enhances the M-car characteristics of the X3M and X4M.

Designed to be versatile, this valved exhaust system offers a balance between everyday usability and aggressive, motorsport-inspired sound. Whether you're pushing your X3M or X4M to the limits on the track, carving canyon roads, or simply enjoying a comfortable city cruise, this system offers a tailored exhaust note for every occasion.

Two Distinct Configurations:

• Single Mid-Pipe Configuration: Unlocks the full, raw power of the S58 engine. This configuration improves the factory sound, creating a more aggressive and engaging tone that brings the X3M/X4M to life. It enhances sound clarity and flexibility, perfect for enthusiasts who want a pronounced exhaust note that reflects the true character of an M car.
• Equal-Length Resonated Full Exhaust: For those desiring an even more refined sound, the Equal-Length Resonated System smooths out exhaust pulses, creating a high-pitched, exotic sound similar to European supercars. This configuration eliminates uneven frequencies, delivering a seamless and smooth exhaust tone that will captivate every driver.

Precision Engineering & Seamless Integration:
The system integrates fully with the factory M1/M2 drive modes, allowing you to switch from a quiet, civilized tone to a loud, aggressive roar with the push of a button. For enthusiasts who want total control, an optional independent valve controller is available for manual sound adjustment at any time.

Premium Material Choices:
This exhaust system is offered in two material options:

• Stainless Steel for superior durability and corrosion resistance.
• Titanium for a sharper, more pronounced exhaust note, while also significantly reducing weight.

Both materials ensure maximum strength and heat resistance for reliable performance under extreme conditions.

The Valvetronic Valved Sport Exhaust System replaces the factory cat-back section, delivering measurable improvements in power, throttle response, and exhaust sound without sacrificing daily drivability or long-term reliability.
