Default Does anybody know what is the diameter of the OEM exhaust on the 2.7T?

I put my hands on a RS6 exhaust and I need to get adapters to fit it on my A6. I believe that the OEM is 2.25" but I am not sure. Can anybody confirm that?

Default 2.5, you'll need a pipe expander attachment for the downpipes since

i think you haven't done downpipes[yet]...and yours are 2.25 from the manifold down.

if you have air tools it might work using an expander...it'll whack the diameter out to accommodate<ul><li><a href="http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=37354">one of these</a></li></ul>
