Product Information "Exhaust.one 3.5'' Exhaust System for BMW 440i OPF F32 Coupé"

We present to you our 3.5" valved exhaust system for the BMW 440i OPF Coupé with 326 HP. No other provider on the market offers a comparable combination of maximum volume and brute sound like Exhaust.one!

Why choose the Exhaust.one exhaust system?

Maximum Volume: With our large pipe diameter, we have developed an unparalleled exhaust system that maximizes your driving pleasure.
3.5'' Pure Sound: Deep, dominant, and powerful sound – these are just a few descriptions of our sport exhaust, specifically designed for the OPF-equipped BMW.
Handcrafted from Premium Materials: For long-lasting driving enjoyment, we only use the best materials, such as V2A L304 stainless steel.
Exempt from Registration: Thanks to the ECE approval and our ECE module, the exhaust system is exempt from registration.

Intelligent Valve Control

The heart of our exhaust system is the smart valve control. With Exhaust.one's ECE module, you are guaranteed to be safe and legal on the road.

Perfect Add-ons

If you're still looking for an ECE-approved downpipe, we offer the perfect option for your BMW. You can also find the corresponding intake system with us for even more performance.

Important Notes

Not all original BMW valve modules control the exhaust valves according to the official ECE guidelines. This is why we offer our own valve control module, which fully complies with legal requirements and legalizes the Exhaust.one system.
If you have other modifications on your 440i with OPF, or plan to make some soon, please note that our ECE approval will no longer be valid. In this case, a combined inspection at the TÜV will be mandatory.
