Product Information: "Exhaust.one 3.5'' Exhaust System for BMW 435i F32 Coupe"

We present to you our 3.5" valve exhaust system for the BMW 435i Coupe with 306 HP. No other provider on the market combines maximum volume and powerful, aggressive sound as perfectly as Exhaust.one!

Why you should choose the Exhaust.one exhaust system

Registration-free with our own valve control module: Thanks to ECE approval, our valve exhaust system is registration-free in all countries according to ECE regulations!
Intelligent valve control: Our smart ECE module ensures that you are driving legally. It knows exactly how to control the valves to meet the legal requirements.
3.5'' pure fun: With a pipe diameter of 3.5", we have created the ultimate sound for you: deep, powerful, and dominant – a truly unmistakable sound experience!
Maximal legal loudness: We push the limits of legality and guarantee that you won't find a louder straight-pipe system on the market that can be driven with such peace of mind.
100% perfect fit: With years of experience in the tuning sector, we guarantee that every one of our exhaust systems fits perfectly.

Additional options

If you're looking for a matching, ECE-approved downpipe, we have the perfect addition for your BMW. The advantage: It remains registration-free even when combined with our exhaust system.

And if that still isn't enough, we also offer the matching intake system for even more performance and sound.

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 system.
If you have made other modifications to your BMW 435i, such as an upgraded intercooler, intake system, or performance enhancements, our ECE approval becomes void. In this case, a combined inspection by the TÜV is required.
