i bought 2.5" pipe and it was too big for the exhaust on my 2002 H6 and 2003 H6, both of which seem original.
so i think the larger diameter is 2.25" by the muffler-midpipe connector.

2.5 inside-diameter pipe would be easiest.
by flex pipe do you mean the cheapy stuff they sell in autoparts stores off the shelf? that stuff is like a matter of months.Flex-pipe doesn't last long, though.
that cheap stuff is amazingly flimsy and horrid.The cheap stuff, due to rust, so stainless should work.
LOL. indeed, really? get a bigger pipe, clamp it down?Slightly oversize on tjhe pipe will hide a multitude of sins (bends).
