Should I upgrade my Audi A4's exhaust system?

I've been thinking about upgrading my Audi A4's stock exhaust system to improve performance and sound. Is it worth the investment? Will it void my warranty? Is there anything else I should consider?

In my experience, upgrading the exhaust system on an Audi A4 can definitely improve performance and give it a deeper, more aggressive sound. However, it's important to research and choose a reputable brand to avoid any potential warranty issues.

I upgraded my A4's exhaust system and couldn't be happier with the results! It added some extra horsepower and gave it a growl that turns heads. As for the warranty, make sure to check with your dealership to see if it will void it.
