Top 5 Reasons Most Supercars Have Titanium Exhausts

Gone are the days when automakers had to rely on heavy steel and iron for manufacturing cars. Even for the bespoke, high-quality cars, the most precious metal used to be aluminum, but that has changed now that material science and technology has advanced.

After extensive use in the aerospace and aviation industry, Titanium has made its way into the automotive and performance car industry for good. It has now become the most sought-after material, especially by the manufacturers of unique – high-end supercars, and its performance totally justifies its popularity. It is particularly used for crafting high performance exhaust systems.

Let’s understand what makes Titanium such a sought-after material and why most supercars have titanium exhausts.

1) It is Super Robust

The main reason manufacturers love to use titanium in the exhaust systems of their performance cars is its strength and rigidity. As compared to steel, titanium is much more rigid and bears substantial stress without any deformity or permanent change in its properties.

Bearing the high stresses that ultra-performance powertrains in supercars and hypercars generate, makes Titanium a popular material among carmakers.

2) Extremely Light

Supercar designers and engineers have one main goal, make a fast badass car. One of the ways of doing that is to make a car as lightweight as possible. This makes power gain and torque figures more practical and cars with lightweight frames and components offer much better dynamics with sharper handling.

Titanium is a very lightweight material and despite having the strength of a juggernaut, it doesn’t weigh much in comparison to older metals. This allows the manufacturers to improve the power-to-weight ratio, and enhance overall performance without sacrificing quality.

3) Withstands High Temperatures

When that shiny supercar or hypercar is breaking speed records or nailing perfect corners, the exhaust system bears all the grunt of the engine. Breathing all the fresh air and spitting fire, the exhaust system must keep up, and to be that good, it ought to have certain physical properties.

Titanium, along with its other superpower-like properties, is superbly well at withstanding high temperatures. According to experts, Titanium can bear up to 900o C of temperature and this red hot material is ideal for crazy speeds like 300+ mph and ultra-track performance. It doesn’t melt, expand or contract, and doesn’t even flinch, no matter how high the car's operating temperature gets or how fast the car goes. Other components like the tires would fail long before titanium parts will.

4) Perfect for Space Management

Titanium is a space-saving material and thanks to its ductility and shaping properties, it can be designed as per the engineers’ requirements. Space saving is an important aspect when designing a car, because this affects how the car will handle.

With the engine and passenger compartment designed well, Titanium allows the engineers to pack the exhaust system into the little space that’s left. It is the perfect metal to form many optimizable pipe lengths, bend angles, and due to its mechanical properties thickness of said pipes. Saving engineers weight and offering enough of a margin to improve dynamics and performance.

5) Classy Exhaust Note

What good would be an exhaust system if it sounds dull? But you don’t have to worry about it with titanium as this super thin and lightweight material can be tuned to aggressive notes. Rock the gas pedal and you have a brutally roaring exhaust note behind you, with titanium, you truly get the best money can buy. You also don’t have to worry about any stubborn rust at the same levels like you would with other conventional metals like steel.

Supercars have Titanium to thank for their aggressive exhaust sounds, sounds that inspire the youth and the next generation of supercar owners.
