How do I properly maintain the exhaust system on my Audi R8?

I've noticed some strange noises coming from my Audi R8's exhaust system. How often should I have it inspected and cleaned? Are there any recommended products for keeping it in good condition?

It's important to have your exhaust system inspected and cleaned on a regular basis, especially if you use your Audi R8 for high-performance driving. It's recommended to have it checked every 10,000 miles or once a year, whichever comes first.
