While my CDTi 06 plate was parked on the driveway my rear exhaust silence had dropped right down. Because the bottom of the big bracket rusted away totally. The silencer is rusted through behind the bracket. The car is 160k+ and one owner before me used it as a workhorse in a very wet location. So that car is not worth getting expensive parts. Any suggestions on my best options?
Does anyone know, if I fitted a universal back box what would be the minimum acceptable diameter for the inlet to the back box. The ones on ebay seem like 2 inches which is very small. Or is it best to look for a cheap aftermarket system?

Have a chat with Arctic, I believe he has some excellent condition used back boxes that wouldn't cost a fortune

Hi Dave.
I did one got fitted to my tourer, and the other was given to a local chap who likes to drive up and down curbs a lot, which damages the cars drop links, rips off wheel arches and brake and abs sensors as well as back boxes, :shock:

I have telephoned many breakers and they have not seen a Rover 75 in years. I use an angle grinder in my driveway and so is this petrol back box on my CDTi be a good way to go? Would I try and cut to slot together? or buy a link section?

Or could I make this fit? https://www.ebay.co.uk/itm/365551118171
Thanks

You can make anything fit with the right connections.

Thanks I have ordered the V6 new one for £57 delivered. Quite pleased with that price. I am now going to work out if I can bodge a bracket that holds it. As the bottom of the bracket disappeared due to rust

I am waiting delivery of the v6 back box and getting the car ready. How easy is it to angle grind a cut into the old CDTi exhaust pipe. Do I need to get the old exhaust off? Or can I do as I was planning to cut while the exhaust is on the car? thanks.

did mine under the car on axle stands with angle grinder, measure 50 times, cut once :-D

Thanks that is very helpful. Do we measure to slide the CDTi pipe into the V6 silencer? Or cut to use a connector?

ED if it going to slide in then measure for that, but always best to allow a bit more for the first cut then you can always take some off, it makes it hard if you cut short.

I put a V6 back box on my tourer when i had it, a nice gift from Stocktake (Dave) thank you,
Joined it with a long clamp.

Thanks Steve. I have all the screw etc out of the rear bumper (5 screws top, 2 underneath, one each side/wheel arch) and Haynes says lift and pull out. But as very normal with plastic trim etc it does not want to budge and concerned about breaking it.

Any tips on dislodging the rear bumper once all screws are out?

UPDATE - The ends of the bumper by the wheel arch eventually came out by pulling up and out and then worked my way around.
