F&F mufflers are developed entirely within our racing department, and validated only after many tests to find the volumes and characteristics necessary to make the engine work for which they were designed to the maximum!

They are handcrafted, in 0.8mm sheet metal with anodized aluminum silencer.

They are all designed to be mounted directly on our Torsen!
