Exhaust system
Exhaust system
Hi All
Xfire has just passed its MOT again, no problems listed. I have however got a very noisy exhaust baffle sound (rattles at certain revs).
MOT guy said there are no loose brackets, clamps or holes.
Has anybody else had this at all and what was your solution?
Cheers

Re: Exhaust system
Garage has gone over the exhaust system and said it is potentially the cats breaking up, nothing loose or broken externally. I have had a look on the Crossfire Parts list to identify what replacement parts I will require. Can somebody please confirm if I am right with my understanding?
If its the cats, am I looking for items 1 & 2 from the diagram plus items 6, 7 & 8?
I had always assumed the cats came as single items for each side and were just bolted into place, i.e. no pipework came with them.
Many thanks

Re: Exhaust system
This happened on PU truck I had some years ago. Luckily I was able to remove the pipe just after the cat, and remove the loose honeycomb rattling around in there. Chiseled out the rest and no problems since. The omissions program testing had just ended so no problems.

Re: Exhaust system
No loss of power, hangers and shields checked and are OK
Re: Exhaust system
these are not normal honeycomb cats, they are media, so them breaking up is hard to believe.
I have my secondaries in my shop, if I can get a chance when I get home I will take a pic, if not ight be another week till I get back to my shop.
there is cata clean that runs exhaust hot and cleans cats

Re: Exhaust system
crap, sorry I forgot to take some pics, I was in a rush, got home at 9 pm and me and wife up at 5 for a extended weekend.
I have never had to do inspections, but also if it was a problem with the cats I would think it would show up on the emissions test.
I have seen threads of people talking about rattling cats but have never seen anyone try some cata clean, or some people that have gutted theirs, they never said what the problem actually is with this style of converter, if it is the cats building up hydrocarbons on the media clumping together maybe a cleaner, but again a notice in loss of power would be noticed due to the restriction.
wish I could hear what yours sounds like

Looking at the Exhaust system Figure 11-110 from the parts catalogue, which is the actual cat, is it the units on the downpipes from the exhaust manifold or the two side by side under the centre line?
Re: Exhaust system
Hi Speedy4x4I have tried to use my mobile on video mode to see if it picks up the rattle on the audio, didn't work. will have another try.

some areas can get away with only having 2 and they can take the back pair off.
Re: Exhaust system
It has been suggested that the two centre line cats are removed, the comb that is causing the rattle is removed, the cats put back and nobody would be any the wiser.
It would be down to the emissions test to see if this is actually the case.
I will keep in digging for more info.
Many thanks

Re: Exhaust system
Hi Speedy4x4
The Xfire went to the garage Wednesday to have minor surgery. Both centre line cats have been "opened" up and either the comb has been removed or welded back into place to stop it rattling. I now have a car that sounds like a car and not an empty tin can full of rusty nails.
The MOT (UK vehicle inspection) is due next May so we will see if it passes the test.
There are no engine management lights on yet, so hopefully all is well.
Many thanks to all that helped out.
Cheers
