Exhaust Back Box Bracket

[ABT]

Hi. On my 2007 1.6 Hdi Exclusive, the back part of the exhaust appears to be perfect and the exhaust is working fine. The bracket around the back box however is rusting away, and there is now slight movement of the back box. I've rang a couple of local independant garages and have been told that the bracket can not be bought and that a whole new back box is required. Can anyone confirm that this is correct, and also would a universal exhaust bracket work as a replacement for the rusting bracket? Many thanks.

You can not buy the bracket. A fix is to weld what is left to the box.

On our 2003 C3 the original exhaust was one piece but after market ones such as from Euro carparts (and Citroen) are in 2 sections and cost about £100 vs about £350 from Citroen. However, the one I used resonates at about 2500 rpm and spoils the car, but I am hoping after some use it will improve. I think it may be a Klarius one from Euro carparts.

Just had mine done and you will need a new back box.However as i found out the original exhaust is in one piece so you have to buy the full system.It will then come in two parts,middle and back box.

If the middle bit is still ok, Haynes explains where to cut off the back bit (there are a couple of dents in the pipe) and then Citroen supply a connecting piece (about £15) to join the 2 sections or an after market one will have an overlapping section that nips up with a U-bolt and a bit of exhaust assembly paste. The after market back box supporting bracket is welded on to the box on the Euro carparts one so you could not just buy a box and only use the bracket. From memory, a Citroen back box was about £150 so is a bit dear if you just want to use the bracket.

Hi - I had my exhaust replaced about a month ago. The original backbox was square-ish, but the new one is cylindrical. Is this a Klarius like you describe? It came in two sections as well. Mine has been rattling something fierce (although only intermittently - can't recall at what rpm off hand). I'm thinking of taking it back to the garage to complain, but if it is the same as yours then perhaps the rattling is normal? Has yours improved over the last month?

 

Cheers

Our exhaust has not improved yet and it resonates (rather than rattles) at idle as well as at higher rpm. It has still not done many miles but is unlikely to fill up with soot and improve since the engine burns cleanly, the old exhaust was clean inside. The back box is round rather than squarish as the original. I intend to have a look under the car to see which part is making the noise. I fit it myself and it is not catching on anything and the heat shield is not loose which could be causes of a rattle. A rattle could also be a bit of assembly paste inside the exhaust, I was carefull not to use too much at the middle/back section joint - if this is a cause of a rattle then the sections are likely to need removal so it could be tipped out.

 

Rattling/resonating should not be normal.

Thanks for the reply Paul. It sounds like we likely have the same/ similar type of exhaust fitted. I've been paying attention to the rpm at which it makes noise - the loud rattle is at idle, although sometimes also randomly at higher rpm. It also resonates at about 2500, much like you describe. I agree - neither should be normal. Looking underneath, it is clearly shaking at idle but I can't see it hitting anything and the heat shield seems ok. It's hard to be sure though with the car on the ground. I'll be taking it back to the garage this week and expect them to sort out the loud rattle at least (free of charge). I'll let you know how I get on.
