Description
The Ultimate Aesthetic & Sound Upgrade
Our Single-In Dual-Out Valvetronic Muffler is engineered for the driver who wants the aggressive presence of a split rear exhaust system combined with total sound control. The integrated high-grade pneumatic valve system allows you to bypass the muffler’s internal baffling on demand, freeing up exhaust flow and delivering a smooth, throaty roar that enhances your vehicle’s character.
Engineered for Longevity
True to our commitment to quality, this system avoids the use of stepper motors, which are prone to rattling and heat-related failure. Instead, we utilize vacuum-actuated valves that provide a tighter seal and more reliable operation, ensuring your valvetronic system stays crisp and leak-free even under heavy performance use.
Premium T-304 Construction
Built to handle everything from coastal salt air to high-heat engine cycles, the T-304 stainless steel construction ensures your muffler remains corrosion-free. The polished finish is designed not just for performance, but for a premium look that lasts.

Absolutely amazing product,car sounds incredibly aggressive with open valves and still has a deep subtle roar when valves are closed. Product is neat and shining with a system that operates to perfection

One word for this product – AMAZING!
I had this fitted on my BMW and the car now sounds like a beast. The valvetronic option is a great feature if you are travelling with kids or doing long distances, being able to control the sound there is a plus. I also have to give it to the after sales support I got from BNB! from updates about the delivery tracking to assisting with helping find workshops for installation.
Best service by far!
