You have to preserve the O2 sensor for it to not trigger the check engine light and be smog legal. If there isnt a port for it in the new system, you can have any muffler shop cut the OEM one out of the stock exhaust and install it in the new system. http://www.germanonly.com

Does GermanOnly.com do the install?

They can...the shop is in Orange County, Ca. But the system is a direct bolt in replacement. You could do it with a friend on the driveway if you had 4 jack stands... audi, S8 after market exhaust, S8 tuning, A8 tuning
