The Audi S4 is known for its impressive performance and luxurious features, but even the best vehicles can benefit from upgrades. One of the most impactful modifications I’ve made to my Audi S4 is the installation of a new downpipe, which set me back about $1,200. In this article, I will share my experience with this upgrade, detailing the performance enhancements I noticed and whether it was worth the investment.
Understanding Downpipes
A downpipe is a crucial component of a vehicle’s exhaust system, connecting the turbocharger to the rest of the exhaust system. Upgrading to a high-performance downpipe can lead to significant improvements in exhaust flow, which translates to better engine performance. Here are some key benefits of a downpipe upgrade:
- Increased horsepower and torque
- Improved throttle response
- Enhanced exhaust sound
- Better turbo spool time
Why I Chose to Upgrade
After owning my Audi S4 for a while, I began to feel that the performance could be improved. I did my research and found that many owners recommended a downpipe upgrade as one of the best modifications for enhancing performance without sacrificing reliability. The combination of increased power and improved sound made it a tempting choice.
The Installation Process
Installing a downpipe can be a challenging task, especially for those who are not mechanically inclined. I opted to have a professional perform the installation, which took about four hours. Here’s a brief overview of the process:
- Lift the vehicle and remove the undertray.
- Disconnect the existing downpipe from the turbo and exhaust system.
- Install the new downpipe, ensuring all connections are secure.
- Reinstall the undertray and lower the vehicle.
Performance Improvements
Once the new downpipe was installed, I was eager to take my Audi S4 for a test drive. The difference was immediately noticeable. Here are some of the performance improvements I experienced:
- Increased Power: The car felt significantly more powerful, especially in the mid-range RPMs. I could feel the extra horsepower during acceleration.
- Better Throttle Response: The throttle response was sharper, making the car feel more responsive to my inputs.
- Enhanced Sound: The exhaust note was deeper and more aggressive, giving the car a sportier character.
- Improved Turbo Spool: The turbo seemed to spool faster, leading to quicker acceleration and a more exhilarating driving experience.
Is It Worth the Investment?
After living with the downpipe upgrade for several months, I can confidently say that it was worth the $1,200 investment. The performance enhancements have made my driving experience much more enjoyable, and the added sound gives the car a personality that I love. For anyone considering this upgrade, I would recommend it, provided you are also willing to invest in supporting modifications, such as a tune, to maximize the benefits.
Potential Downsides
While the benefits of a downpipe upgrade are significant, it’s essential to consider potential downsides as well:
- Check Engine Light: Depending on the vehicle and the downpipe used, you may encounter a check engine light due to increased exhaust flow. A proper tune can often resolve this issue.
- Noise Levels: The enhanced exhaust sound may be too loud for some drivers, especially during regular driving conditions.
- Legal Considerations: In some regions, aftermarket downpipes may not be street legal, so it’s crucial to check local regulations.
Conclusion
Overall, upgrading to a performance downpipe has transformed my Audi S4’s performance in ways I never anticipated. The increase in power, improved throttle response, and enhanced exhaust sound have made my driving experience much more enjoyable. If you’re considering a similar upgrade, I encourage you to weigh the pros and cons and consult with professionals to ensure a smooth installation process. With the right modifications, your Audi S4 can reach new heights of performance.
