Scott,
Funny, I saw those earlier today or maybe it was yesterday. They look great... impressive in fact... but I think the price was like 1800 GBP. That would put them north of $3600 not including shipping, etc. Yikes.
I can still get a set of 993 HEs, flip the flanges, get a muffler and have pipes fabbed for less than $1000. Even new the 993 HEs are not nearly as shiny as those things are, though.
