Dealers if you are willing to hire your bum out, if not, I would try the breakers, else I would use this opportunity and go to an exhaust fabricator and have one made.

Been through this one - might be worth you checking the centre resonator also as chances are it will also be on its way out behind the box at the joint (between box and cats).

A new stainless cat back will cost you around £400 but issues with noise - some people have bought these with no noise so its a mixed bag but worth shopping around for the quietest one. Some welds on mine are shot also after 2 years use.

For me, mine is quiet until around 2k revs where it creates a hell of a drone noise within the cabin. Novelty at first but cant live with it now. Mine is a free flow. I am making my own at the moment and just need a few hangars to start to put it together ....oh and of course some dry weather which will be no time soon ! Cost for parts so far is £68 but will expect it to finally be around £90. Will post how I done this once I am ready to do so - doesn't help you out now though.

There is a set of back boxes on eBay at the moment OEM used ones for (I think) £250 which is cheap compared to £800 new but you do take the risk of them rotting quicker compared to new as they are used.

You will not only be hiring your bum out if you buy a new one - I think organ donation would also come into play at a 2013 quoted cost of an oem middle and box replacement at £2700!!!

Exactly the same happened to me 2 months ago. It was not even rusted, but simply break-off. Get quote from halford - £660 part + "labour" (that is 2 bolts and 6 rubber holders ~15min when car is raised), didn't even bother to quote dealership. As mentioned "custom-made" ones would cost ~£400 - I got 2 quotes MIJ £354.99 + fitting, Longlife -£699 with fitting, neither would agree to post it and both required visit their workshop somewhere in midlands (that is for sake of "professional fitting").

As my one was not rusted, just got to the local eastern european service to check what is the condition of entire cat-back and end up paying £60 just to weld it back to place. Just chatting with them I find out that if that would happen again or if I want an "upgrade" they can do "end-to-end" titanium for 700eu (emhh.. that is £489 from engine to the end), "IS-F style quadruple tailpipes" included as an option at no cost. Not sure if I trust them (+ it takes 2-4 weeks for it being shipped to UK .. and I guess fabricated), but sounds reasonable upgrade.

As for used ones from breakers - there are not many IS250's, majority are IS220d's and you would get no warranty that same won't to happen few miles after fitting.

I would say - check whole rear section - if it is rusted then consider changing... if it is like mine just ask to weld it back.
