Hey all, im going to delete the main cats on my car and was enquiring the od size of the exhaust pipe. Im just going to order a section of stainless tubing and weld it in place of the cat. I think its 2.5 but I'd like to be sure before I order, thanks.

I used 2.5", it's very slightly smaller that the OE exhaust, at least at the slip connections, but it worked fine.

When I was looking into replacing the flex pipes I found that the downpipes were 65mm (2.55906in).
03 RS6 Avus/Ebony #905593 resurrected 6MT, 04 Avalanche Z71, 87 T-Bird Turbo Coupe (351W T5), 04 Aprilia RSVR Factory
That sounds about right.

European car so parts are in metric. 65mm pipes.
'02 S6 Avant Silver - Pokey | Carbon Black/Ebony RS6 w/ stuff - darn quick | '03 Daytona Grey/Ebony RS6 w/ more stuff - quicker yet | '91 NSX CDN issue with 6spd & BBSC - quicker yet and then some | '87 Buick GNX OEM clone w/ lots of stuff - quickest hands down
