RS exhaust tips
<img src="http://www.carbonLORD.com/Audi/RS6exhaust1.jpg">
Might want to check out <a href="http://www.magnaflow.com/02product/tips/doublewall.asp">Magnaflow</a>, which is a popular tip choice around here, but I am unsure if they make a powder coat or black anodized tip, if you were searching for a similar black RS 6 tip look.
Unless someone cuts the tips off ther RS 6 (exhaust) it will be slim to none on sourcing OEM RS 6 oval tips. Although, I have read a thread from time to time on the <a href="https://forums.audiworld.com/rs6/">RS 6 Forum</a> as well as the <a href="http://www.rs6.com">RS6.com</a> forum where owners were asking where they could chop off and weld different tips to their beast. Never hurts to ask, and I'd ask around these two places first.
Good luck.
If your interested, I purchased 2 of them for my 4.2 but decided not to install them because I'm considering selling my car. If your interested, email me at samuely@yahoo.com
good luck
