The Audi S4 is known for its performance and luxury, but many enthusiasts seek ways to enhance its capabilities further. One popular modification is the installation of an aftermarket exhaust system. In this article, we will explore whether aftermarket exhausts are worth the investment, specifically focusing on the potential to boost power by 20 horsepower for under $1,200.
Understanding Aftermarket Exhausts
Aftermarket exhaust systems are designed to replace the factory exhaust components of a vehicle. These systems can improve performance by enhancing exhaust flow, reducing back pressure, and often providing a more aggressive sound. For the Audi S4, which features a supercharged V6 engine, an aftermarket exhaust can be particularly beneficial.
Benefits of Aftermarket Exhausts
- Increased Horsepower: Many aftermarket exhaust systems are designed to increase horsepower by allowing exhaust gases to exit the engine more efficiently.
- Improved Sound: Aftermarket exhausts often produce a deeper, more aggressive sound that many enthusiasts prefer over the factory setup.
- Reduced Weight: Some aftermarket systems are lighter than stock exhausts, which can improve handling and performance.
- Enhanced Aesthetics: Upgrading to an aftermarket exhaust can improve the visual appeal of the vehicle with polished tips and unique designs.
Power Gains: What to Expect
When considering an aftermarket exhaust for the Audi S4, many users report power gains of around 20 horsepower. This increase can be attributed to improved exhaust flow and reduced back pressure, allowing the engine to breathe more freely. However, actual gains can vary based on the specific exhaust system chosen and other modifications made to the vehicle.
Cost Considerations
One of the most appealing aspects of aftermarket exhaust systems is their affordability. Many quality systems can be purchased and installed for under $1,200. This price point makes it an attractive option for those looking to enhance their Audi S4’s performance without breaking the bank.
Installation Process
Installing an aftermarket exhaust can be a straightforward process for those with basic mechanical skills. Many systems come with detailed instructions, and there are numerous online resources available. However, for those who are not comfortable performing the installation themselves, professional installation is recommended.
Potential Downsides
While there are many benefits to installing an aftermarket exhaust, there are some potential downsides to consider:
- Increased Noise: Aftermarket exhausts can be significantly louder than stock systems, which may not be suitable for all drivers.
- Legal Considerations: Some aftermarket exhausts may not comply with local noise regulations, leading to potential legal issues.
- Warranty Concerns: Modifying the exhaust system may void certain aspects of the vehicle’s warranty.
Choosing the Right Exhaust System
When selecting an aftermarket exhaust for the Audi S4, it’s essential to consider several factors:
- Material: Exhaust systems are typically made from stainless steel or aluminized steel. Stainless steel is more durable and resistant to rust.
- Type of Exhaust: Consider whether you want a cat-back system, axle-back system, or header-back system based on your performance goals.
- Sound Level: Choose a system that matches your desired sound profile, from mild to aggressive.
- Brand Reputation: Research brands and read reviews to find a system that has a good track record for quality and performance.
Conclusion
In conclusion, aftermarket exhausts can be a worthwhile investment for Audi S4 owners looking to boost power and enhance their vehicle’s sound and aesthetics. With the potential for a 20 horsepower increase at a reasonable cost, these systems offer a balance of performance and value. However, it’s essential to weigh the benefits against the potential downsides and choose the right system for your needs. Overall, for those who are passionate about their Audi S4, an aftermarket exhaust could be a significant step toward achieving a more exhilarating driving experience.
