You can get a lot of car for $40,000. The Ford Mustang GT, Subaru WRX STI and Volkswagen Golf R all come to mind, but each is still cheaper than the QuickSilver Exhaust Systems Titan, titanium cat-back exhaust for the Bugatti Veyron.->ke1112 At £26,760 or a little under $42,000, QuickSilver claims it’s the most expensive exhaust system in the world.

In this video, fitted to a Bugatti Veyron Grand Sport Vitesse, it sounds absolutely monstrous. Titanium systems tend to resonate higher, giving the exhaust note a slightly higher timbre, and in this case it definitely makes the Veyron’s quad-turbo, 1,200-horsepower, 8.0-liter W12 sound a bit more unhinged. Veyrons have a unique sound anyway, and while you would never say they sound bad, this gives it more of an edge. We’d love to hear what it sounds like under load outside a garage.

Unless you’re a certified Bugatti mechanic (cool job, by the way), installing QuickSilver’s Veyron exhaust doesn’t look like something you would want to attempt. Lots of expensive carbon-fiber bodywork has to come off, including the rear deck lid and a sizable panel above the rear bumper.

As pricy as they are, titanium exhausts don’t really offer many tangible benefits for the street over traditional steel systems, which is why they’re use is mostly limited to race cars->ke148 and exotics. They heat and cool faster, but that only provides slightly more power at low engine temperatures. They’re considerably lighter, but when you’re working with a two-ton, multi-million dollar car, you’re probably just doing it because you can. Mostly, they just sound cool and turn pretty colors when they’re heated up.
