And how Tubi Style helps it reclaim the sound it deserves


The Ferrari 308 GTBi is far more than just a transitional model in Maranello’s history. It marks the shift between two automotive eras: from the raw passion of carbureted engines to the precision of the Quattrovalvole. The GTBi represents Ferrari’s first step into a new decade — one that demanded cleaner emissions, global expansion, and a more restrained engineering philosophy — all while preserving the iconic Pininfarina silhouette that would forever define the 308.


Produced between 1980 and 1982 in just 494 coupe units (plus 1,743 GTSi spiders), the GTBi is now a rare sight. Often overlooked in favor of its more celebrated siblings, it nonetheless commands the attention of true connoisseurs. Because those who really know Ferrari understand that this berlinetta holds the key to how the brand faced the challenges of the 1980s without compromising its soul.

A car for those who truly appreciate the details.
Visually, the GTBi stands out through a series of subtle but meaningful features:


  • Engine: 2.9-liter V8 with Bosch K-Jetronic mechanical injection (214 hp EU / 205 hp US), replacing the four Weber carburetors of the earlier GTB.
  • Engine hood: A slight central bulge — not present on the carbureted model.
  • Wheels: Unique 390mm TRX metric wheels, often swapped today for more conventional 16-inch rims.
  • Interior: Darker dashboard, matte Veglia gauges, understated trim.
  • Rear badge: “308 GTBi,” with either a red or chrome “i” depending on market.

Compared to the later 308 Quattrovalvole, the differences are even more pronounced: black valve covers instead of red “quattrovalvole” ones, slimmer side air intakes, and above all, lower power output (214 vs 240 hp).

Tubi Style stands beside legends.

Few manufacturers would invest in developing a custom exhaust for such a limited-production car — but for us, numbers have never defined worth.
We’re drawn to cars with authentic souls, and our goal is to help them reclaim what makes them special: a sound that reflects their heritage and brings their character to life.

The 308 GTBi is a perfect example.
From an acoustic perspective, it carries a more subdued legacy. Where the carbureted GTB delivered a raw, visceral crescendo, the GTBi was tuned with restraint — refined, almost polite. The V8 still beats with Ferrari DNA, but its voice feels muted, shaped by a new technical etiquette imposed by the era.

Today, that difference matters more than ever.

Sound isn’t just a detail — it’s integral to the Ferrari experience.
A GTBi that’s pristine in body and mechanically sound but fitted with a tired or corroded exhaust can feel flat, deprived of the emotional spark you expect the moment the engine turns over..

This is where Tubi Style makes the difference.

For us, replacing an exhaust isn’t just a matter of swapping parts — it’s about bringing a car’s soul back to life.

Every Ferrari has a voice. And with the 308 GTBi, that voice deserves to be heard. That’s why we’ve developed different solutions to suit the needs of collectors, restorers, and enthusiasts alike.

If you’re restoring a GTBi with absolute authenticity in mind, our Heritage Line is for you — a faithful reproduction that protects the car’s collectible value while keeping its factory look and feel completely intact.

If your priority is reliability and peace of mind for everyday enjoyment, we offer enhanced replicas. These systems look identical to the originals, but benefit from modern construction techniques for added durability.

And for those who believe a Ferrari should sing with its full voice, we offer a sport exhaust that transforms the driving experience — richer, more present, and unmistakably Ferrari. All without compromising the car’s original identity.

But with the GTBi, there’s a particular detail that matters: its K-Jetronic mechanical injection system doesn’t adapt automatically like modern ECUs. So, when installing a sport exhaust, proper tuning is essential. That’s why we collaborate directly with specialist mechanics — to ensure that the end result is not only thrilling to drive, but also perfectly safe for the engine.


More than just performance — it’s about emotion.

On a car that’s seen more than four decades of life, wear and tear is only natural. Exhaust systems in particular are often the first to suffer, corroding over time and robbing the car of both performance and soul.

A Tubi Style exhaust doesn’t just restore what’s been lost — it takes it a step further. Built in high-grade stainless steel, with certified documentation and a lifespan that’s practically unlimited, it’s a technical upgrade that also adds real value to the car.

For a collector, that means preserving the investment. But more importantly, it means being able to enjoy the car — not just as a showpiece, but as a living, breathing Ferrari.

Because while the timeless lines of Pininfarina will always be admired, it’s the sound that stirs the senses.

With Tubi Style, the 308 GTBi is returned to what it was always meant to be: a Ferrari that captures the spirit of a unique era — a time of change, challenge, and bold innovation that brought the Prancing Horse into the modern age.
