Milltek 100 cell Catalytic Convertor

[PeteGray]

Taken off my 39,000mile CSL. Not 100% sure how many miles it's done as the car came with it already fitted (original refitted).
The previous owner, I believe, said that he put it on at 34,000 miles. It appears to be in excellent external condition and did sound better than the original when fitted.

I genuinely don't know what this is worth, so would invite offers. To comply with this sites rules (moderators?) I'm happy to post this as a question in the general section first and take down this advert.
