You probably picture a luxury Volvo S90. It has sleek lines and clever tech. Safety is a big focus. That’s its usual image, right? But here’s the thing. This car has a secret world. Aftermarket parts make it truly unique. Exhaust system upgrades are very popular. Many car fans really love them. Today, we’ll dive into this world. We’ll see what exhausts fit the S90. How do they change sound and power? And why might you want one? Let’s find out together, shall we? This journey will be quite interesting.
Understanding Your Exhaust System
Let’s set the stage a bit, okay? What does an exhaust system actually do? Why is it so important for your car? This system moves all those burnt gases away. It takes them right from the engine. It also helps cut down on bad emissions. It’s a complex setup, you know. First, you have the exhaust manifold. Then comes the catalytic converter. After that, there’s a resonator. Finally, a muffler quiets things down. Each part plays a big, big role.
Now, the exhaust choice truly matters. It changes your car’s sound. It also impacts how it performs. An aftermarket system often boosts airflow. This means your engine works better. You get more horsepower, too. A study by [Automotive Performance Company](https://www.automotiveperformancecompany.com) once said this. Aftermarket exhausts can add 10-15% more power. That depends on how it’s set up, of course. Can you just [imagine] that extra push? Feeling it when you hit the gas? Honestly, that’s what we’re really talking about. It makes a difference.
A Little History on Performance Exhausts
Honestly, performance exhausts aren’t new at all. People have modified cars for ages. Early racers often just removed mufflers. This boosted power, but made them super loud. Then, in the mid-20th century, companies started designing better ones. They used science to improve flow. Brands like Borla were early pioneers. They focused on optimal exhaust gas scavenging. That means getting gases out faster. It was all about making engines breathe better. From those simple beginnings, we’ve come so far. Modern systems are truly works of art. It’s quite a history.
But Are There Any Downsides?
Now, before we get too carried away, let’s be real. It’s not all about big gains and cool sounds. Sometimes there are trade-offs involved. What about your warranty? That’s a big question for many drivers. Some dealerships might not like modifications. You should always check with them first. Also, think about noise regulations. Some aftermarket systems are just too loud. They might not be legal where you live. Plus, there’s the cost to consider. High-quality systems can be pricey. Is the expense worth it for you? It’s something to really think about.
Another thing, installation complexity varies. Some systems are a simple bolt-on. Others require professional help. You might even need an engine tune. This ensures everything works together. Without it, you could face issues. Fuel economy could also shift slightly. Sometimes it improves a bit. Other times it might get worse. It depends on the specific design. It makes you wonder, doesn’t it? Every decision has its own path.

So, we’ve seen some great options. Now, let’s talk about the how. How do these systems really change sound? And what about that power output? It’s truly fascinating, honestly.
The Science of Sound
The noise from an exhaust has many factors. The material matters a lot. Muffler design is also key. Even pipe size plays a part. Bigger pipes let gases out fast. This usually means a louder sound. Materials also change resonance. Stainless steel often sounds sharper. It’s more aggressive than mild steel. Think about that difference, you know? Most aftermarket systems add 3-5 decibels. A standard S90 is around 70 dB. Aftermarket versions hit 75-80 dB. That’s a noticeable increase in sound. Quite a change.
Boosting Your Power
More power comes from better airflow. Exhaust gases leave the engine easier. This lets the engine breathe better. It’s a big help for turbo engines. The Volvo S90 has those. Better flow means quicker turbo spool. Your throttle response also improves. A [Car and Driver](https://www.caranddriver.com) study found this. Aftermarket exhausts add 5-20 horsepower. It really depends on the system. It also depends on your engine. This can totally change driving dynamics. What a difference, right? I am excited by such possibilities.
