Description
Unlock the true sound potential of your BMW E46 M3 with the Valvetronic Valved Sport Exhaust – a precision-engineered section 3 upgrade designed to dramatically enhance both exhaust tone and driving experience. After an intensive 8-month development process, this system delivers an unmatched audio transformation for the S54 engine, with full control over sound levels at the push of a button.
Constructed from high-grade brushed T304 stainless steel or ultra-lightweight Ti 6Al-4V Grade 5 titanium, this valved rear section replaces the factory suitcase-style muffler. With the valves open, the S54 engine’s naturally aspirated character comes alive with a raw, engaging, motorsport-inspired sound across the entire RPM range. With the valves closed, the system reverts to a stock-like, subdued tone—ideal for quiet neighborhoods or daily driving.
This section 3 exhaust integrates seamlessly with the factory section 2 midpipe, providing a direct bolt-on solution without the need for permanent modification. While the system may be adaptable to certain aftermarket section 2 components, Valvetronic Designs only guarantees fitment with the OEM section 2.
Weighing approximately 8 lbs less than stock in stainless steel and 18 lbs less in titanium, this system not only enhances acoustics but also reduces rear-end weight for better balance and responsiveness. Precision TIG welding ensures durability, strength, and craftsmanship that matches the high standards of the E46 M3 chassis.
