sounds like waaayy too expensive to me..!
Having just purchased a set this week, it seems a fair price to me, New ACT pipes were about £220 and they go up from there to over £400. The flee bay ones (look like ACT cones) also have the Zirtec heat reflecting coating on them which is not cheap so all in all not bad value. As somebody has mentioned you could knock the internals out of your cats if they are dead but come MOT time you will need a set to pass the test.The ones on EBAY look like a set I could have made judging by the cone shape, cone length and flange shape. Would have to see the welding to confirm though. These would have originally sold for between £180 and £220 depending on when they were originally purchased. The coating would have been put on later by somebody else. Since the materials were very high quality there is no reason why they shouldn't hold their value especially as these are coated too.
Oh, I don't make them anymore by the way

Well yes possibly. Not sure about not flowing as they'll essentially be empty tubes. They will more than likely sound less good than a purpose made unit. But the op said the decat on flea bay was "waaay" to expensive so was providing the cheapest option.
Fair enough regarding the cheapest option 
. When I was developing the "NTEL" decat pipes I used my own car on a rolling road (hired for a couple of days 
). I tested 5 different variations one of which was empty cat cans. These actually flowed worse than the cats. I put this down to having 3 pipes going into a 4.5" dia "barrel" then hitting a really blunt reducing cone. The harmonics must have been all over the place. Didn't really spend anymore time on proving why they didn't work well.NTEL said:

Interesting stuff. I wonder then if you could take an empty cat and basically sleeve it from end to end through the barrel. Could be a cheap option.. but to be honest less hassle is buying the decat. . When I was developing the "NTEL" decat pipes I used my own car on a rolling road (hired for a couple of days ).

well said dave, it does get on my goat a bit when people say things are expensive without realising the work and time that goes into developing the part before actually manufacturing it. .

Get it done. ACT are cheapest *new*, or were when I bought 12 months ago, and a cone will always flow better than a large barrel with a pipe at the end...Pops, Bangs, more power... sounds like (pardon the pun) a bargain to me
You probably won't want to pay Power for the custome re-map tho...
Clive any news on the Track silencers ??? (not checked email recently soz)

Well - So sorry to have 'got your goat' clive. My opinion was based upon the appearance of what the ones on ebay. Certainly not 180 quids worth. In fact the guy that said he used to make them only charged that when new. Everyone knows that secondhand items are at best worth 2/3 of the new cost, so maybe £110 would be more realistic - or are you in the habit of paying full retail price for distinctly second hand goods?

Now don't let CliveF upset you - he's not the best with written word are you Clive ??? 
As regards price for s/hand stuff, all in the TVR commuity are constantly amazed at what we have to pay for some things, both new and s/hand, and it might not be long before some people can sell their Sagaris for more than they bought it new from the Factory... plus decat pipes don;t really wear out do they and these have been 'refreshed' if they've been Zirtech'd...
