Honestly, many G90 owners want just that. They look to aftermarket exhaust systems. These changes affect both the sound and performance. It’s no secret this industry grew a lot. Car lovers are eager for more. They want a better sound from their ride. Also, they aim to boost performance numbers. Let’s dive into this world. We’ll look at these exhaust systems. We will explore their impact on the Genesis G90. What customization choices are there? We will also explore the science behind it all.
The Genesis G90: A Closer Look
Before we talk about exhausts, let’s appreciate the G90. Hyundai’s luxury arm launched it in 2016. It’s a flagship luxury sedan. This car packs a punch, you know? It typically has a big 5.0-liter V8 engine. That engine puts out 420 horsepower. It also delivers 383 lb-ft of torque. Some versions also feature a 3.3-liter twin-turbo V6. That engine still offers impressive power. It makes 365 horsepower. The G90 is known for its smooth ride. Its interior is super luxurious. Cutting-edge technology is everywhere.
However, some owners feel something is missing. The stock exhaust system doesn’t show the car’s full potential. It often sounds too subdued. It’s designed for quiet comfort. This is where aftermarket options step in. They can truly change things. They unlock a more aggressive voice. Imagine the roar you could unleash.
Understanding Aftermarket Exhaust Systems
So, what are these aftermarket exhausts? Simply put, they come from other companies. Not the original car maker. They come in many forms. Think cat-back, axle-back, or header-back systems. Each type offers different benefits. Historically, people have modified cars forever. Exhaust systems were some of the first changes. Early racers needed better flow. They cut out restrictive mufflers. This improved engine breathing. It made cars faster. This DIY spirit grew into an industry. Now, advanced engineering creates precise parts. This progress means better sound and power.
Cat-back systems replace parts from the catalytic converter back. They often use wider piping. This really improves exhaust flow. Axle-back systems replace parts behind the rear axle. They are usually less costly. But they give fewer performance gains. Header-back systems replace everything. This means headers, converters, and all piping. These offer the biggest gains. They are also the most complex.
Statistics show real power boosts. Performance gains can be 5% to 15%. This depends on your car and the system chosen. For the Genesis G90, imagine this. Owners could see 21 to 63 more horsepower. That’s a significant gain! It truly improves the driving experience. I am happy to see such improvements possible. It transforms how the car feels.
Sound Enhancement: A Symphony of Options
Changing the sound is a big draw. The stock G90 exhaust is quiet. It suits the luxury market. But many drivers want more sound. They want a more aggressive noise. Something that matches the car’s power. Imagine driving down an open road. A throaty roar echoes behind you. The right aftermarket exhaust gives that thrill. It truly is exhilarating. Brands like Borla or MagnaFlow offer choices. They are well-known for quality sound. You can often adjust the sound levels. Switch to a quieter setting for daily driving. Then, unleash a more aggressive tone for fun drives. It’s quite versatile.
Some systems offer a deep, resonant rumble. Others provide a higher-pitched, exotic wail. It all depends on design. Muffler design plays a huge part. Resonators also shape the sound. People choose sound based on personal taste. Do you prefer a subtle growl or a full-on scream? The choices are vast.
Performance Gains: More Than Just Noise
But there’s more than just sound. Upgrading your exhaust improves engine efficiency. It reduces back pressure. This improves exhaust flow. The engine can breathe better. This is especially true for powerful cars like the G90. Every bit of horsepower counts there. Honestly, it makes a big difference. Less restriction means more power.
Research suggests better exhaust flow. This can also lead to better fuel efficiency. A study by SCCA showed something interesting. Cars with aftermarket exhausts saw a 2-5% fuel efficiency rise. This might not seem like much. But for a car averaging 20 miles per gallon? That means 1 to 2 extra miles per gallon. Over time, that saves real money. It’s pretty neat. This improvement happens because the engine works less hard. It expels gasses more easily.
Think about it this way. Your engine is like a pump. It pulls in air and pushes out exhaust. A restrictive exhaust is like a clogged pipe. It makes the pump work harder. A free-flowing exhaust is like an open pipe. The pump works efficiently. This leads to more power. It also leads to better economy. It’s quite logical.
Case Studies: Real-World Impact
Let’s look at some real examples. One G90 owner chose a Borla Cat-Back Exhaust System. He documented his installation process online. After installing it, he reported something exciting. He saw a 30-horsepower increase on a dyno. That’s a very substantial gain! The sound was much more aggressive, he said. It gave a satisfying growl when accelerating. He even shared videos.
Another G90 owner tried an AWE Tuning Exhaust System. This system did more than improve sound. It also made the throttle response better. The owner felt the car was more agile. It was more responsive too. Especially during high-speed moves. He remarked how it felt like a completely different car. These real-world stories match the statistics. They show true performance improvements. A reputable tuner, “Speedworks Performance,” noted similar gains. They reported consistent power increases for G90 clients. This validates the claims.
Customization Choices: Tailoring Your Sound and Performance
The world of aftermarket exhausts is vast. It offers many customization options. Do you want a deep rumble? Or maybe a high-pitched roar? There’s an exhaust system for you.
You can choose different materials. Stainless steel is common. It’s durable and resists rust. Aluminized steel is another option. Then there’s titanium. Titanium is much lighter. It offers better performance. But it costs more. Carbon fiber can also appear. It’s light and looks sharp. This affects how your car feels and looks.
Exhaust tip styles also vary. You can customize them. Choices range from slash-cut to straight-cut tips. They can have polished chrome. Or maybe cool blackened finishes. These details make your car unique. It’s a nice personal touch.
Resonators and mufflers fine-tune the sound. Some systems let you remove or add them. This changes the sound level. It’s pretty clever. Some brands offer valvetronic systems. These let you control the sound electronically. You can switch from quiet to aggressive. Just push a button. It’s like having two cars in one. I am excited about how much control this offers. You can adapt to any situation.
A Historical Glimpse: The Evolution of Exhausts
Exhaust systems were once simple pipes. Early cars just needed to vent fumes. Over time, things got complex. Mufflers became necessary. They quieted noisy engines. This made driving more pleasant. Then came catalytic converters. They clean up emissions. This protects our environment. This change happened in the 1970s. It was a big step for air quality.
The performance aftermarket grew from racing. Engineers learned about exhaust flow. They found ways to make engines breathe better. This meant more power. Companies like Borla and MagnaFlow started small. They pushed innovation forward. They made exhausts lighter and stronger. They also crafted specific sounds. Borla began in 1978. MagnaFlow started in 1981. They focused on performance and sound. What began as basic pipes became refined components. They now offer precise engineering. It’s been quite a journey, honestly. It reflects true ingenuity.
Counterarguments and Considerations
Upgrading your exhaust sounds great. But let’s be honest. It’s wise to consider drawbacks too. Some aftermarket systems can be very loud. This might annoy neighbors. It can even be a nuisance daily. Have you thought about that? Poorly designed systems can hurt low-end torque. This happens if back pressure is lost incorrectly. An engine needs some back pressure. It helps with low-speed power.
Local laws also matter a lot. Some aftermarket exhausts are not street-legal. Compliance with emissions standards is very important. This is true in areas with strict environmental laws. Always check your local regulations. Choose systems that meet those rules. This saves you from future headaches. It’s a good thing to remember. A quiet ride also matters to some. A louder exhaust changes the G90’s character. It shifts from pure luxury to a sportier feel. This might not suit every owner. Some prefer the original, silent cruising. It’s all about personal preference.
Future Trends: What Lies Ahead
Technology keeps moving forward. The aftermarket exhaust world will see exciting things. I believe we’ll see more smart exhaust systems. They will link with car tuning apps. Imagine adjusting your exhaust note. You could do it with your smartphone. Change it based on driving conditions! Or your mood that day! It sounds like something out of a movie.
Electric vehicles are becoming more common. Manufacturers might explore hybrid systems. These could create unique sound profiles. They would mimic traditional engines.
