Every engine tells a story.
We write the finale.
Handcrafted, not manufactured. From Maranello, since 1987.
Handcrafted. Not manufactured.
Others have a catalogue. We make your exhaust, for your car, for the way you drive it. Designed, prototyped and hand-welded in Maranello. This is not mass production. It's a one-of-a-kind piece.
The formula of sound
A Lettieri exhaust doesn't sound by chance. Every system is engineered for that engine's specific voice — the timbre under acceleration, the crackle on deceleration, the silence at low speed. Not more noise. The right music.
The technology you don't see — but feel.
4-2-1 Design
4 primaries, 2 secondaries, 1 tertiary. Every millimeter calculated for your specific engine. The result: optimal scavenging, free torque, sound that cannot be imitated.
Silica Felt Insulation
Aerospace-grade silica felt wrapping protects surrounding components, keeps gases hot for optimal flow. Less heat in the engine bay. More durability.
Electronic & Pneumatic Valves
One button. Street sound when you want silence, racing sound when you want to excite. The same car, two characters.
Materials
Aerospace-grade AISI 304 stainless steel. Every tube selected, every TIG weld done by hand. The material is not a detail — it is the guarantee.
38 years of artisan excellence
Fausto Lettieri co-founded Tubi Style in 1987, pioneering performance exhaust systems in the heart of Motor Valley. Today, from his workshop in Maranello, he continues to handcraft every component with the same passion and precision that have defined his career.

What Our Clients Say
“
The Lettieri system is on another level — the sound is raw but refined, and the craftsmanship is visible in every single weld. Fausto truly understands what a GT3 owner wants.

Flew to Maranello specifically to visit the workshop. Watching Fausto hand-weld my exhaust system was worth the trip alone. Three months later, every cold start still gives me goosebumps. This is what Italian craftsmanship means.

“
The 4-2-1 manifold Fausto built for my STO transformed the car. 22 horsepower gained, 8 kg lighter, and a sound that stops traffic in Roppongi. I've recommended Lettieri to every member of my car club in Tokyo.

“
As the owner of a performance parts shop in Zurich, I've installed hundreds of exhaust systems. Lettieri's fit and finish is the best I've ever seen. We became an official dealer six months ago and haven't looked back.
