Product Information "Exhaust.one 3.5" Exhaust System for BMW 440i F32 Coupe"

We present to you our 3.5" valved exhaust system for the BMW 440i Coupe with 326 HP. No other provider on the market can offer you the combination of maximum volume and brutal sound like we do with Exhaust.one!

Why Choose the Exhaust.one Exhaust System?

Registration-Free: Thanks to ECE approval, our valved exhaust system is truly registration-free in all countries according to the ECE directive.
Intelligent Valve Control: Our smart ECE module ensures that the exhaust valves are always controlled in compliance with regulations, so you don't have to worry.
3.5" Pure Fun: With our massive 3.5" pipe diameter, you’ll experience a unique, deep, dominant, and unmistakable sound.
Maximally Legal Loud: We push the boundaries of legality and promise you won't find a louder straight-pipe system on the market that you can drive with such peace of mind.
100% Precision Fit: With our extensive experience in the tuning sector, we guarantee that every exhaust system fits 100% perfectly.

Perfect Additions

If you're looking for an ECE-approved downpipe, we have the perfect complement for your BMW. Since it’s also from us, it remains registration-free when combined with our exhaust system.

If that's still not enough for you, we also offer the matching intake system.

Important Notes

Not every original BMW valve module controls the exhaust valves according to official ECE regulations. That's why we offer our own valve control module, which fully complies with legal requirements and legalizes the Exhaust.one exhaust system.
If you’ve already modified other elements on your BMW 440i, such as the intercooler, intake system, or power enhancement, the ECE approval becomes void, and you must present the car to the TÜV again for a combination approval.
