Although I recently asked this in conjunction with a relevant but different topic, no one come up with any answer, so I thought I'd put in a topic of its own.....
I know they are not available new anymore, but Vauxhall list 2.6 and 3.2 cats with different part numbers, although aftermarket such as those made by cats2u and BM cats list them with the same part number.
I know the after market list some parts as 'one fits all' for all models, whereas VX may have various part numbers, but does anyone know the actual difference between the VX 2.6 and 3.2, and has anyone had experience of fitting 2.6 cats to a 3.2 without issues?
TIA

The difference might actually be manual or auto, and relates only to the position of the rear lamda sensors :-\
-
VX gave me the relevant part numbers from my registration numbers; both of which are autos.....

Cat volume perhaps then :-\

Going back a few years now but I'm sure dealers told me the cats on the Police Omega's are different to standard ? was that due to them being manual cars ? ???

The manuals have shorter rear lamda looms iirc... might simply be due to the different box proportions :-\
Plod ones might be higher volume :-\

I was told the same. We decided that they probably had some extra protection for going 'off road' :-)

The Police spec cats were a different VX part number again from the standard 2.6 auto and 3.2 auto. I think the Police aspect has thrown a spanner the issue - I really wanted know the difference between a 2.6 auto and 3.2 auto cat for a standard (not Police) car because VX list different part numbers.
I also wanted to know therefore if anyone had successfully fitted genuine VX cats from a 2.6 onto a 3.2 without any issue, or if anyone knows whether it may trigger lambda faults as a result if the difference is the composition of the precious metal internally. As you know, the lambda sensor part numbers are the same for 2.6 autos and 3.2 autos........
-
2.6 and 3.2 downpipes full interchangeable.
plod 3.0 ones had different cell count, and thicker box.
-
2.6 and 3.2 downpipes full interchangeable.
In that case, why is the VX part number different for the two auto (non Police) 2.6 and 3.2 models?
-
Could it be that to counter the pre cat issues, they replaced the 2.6/3.2 cats for plod ones?
-
I don't know where the Police cats come into this saga!!!!!!
The standard VX cats for auto 2.6 and auto 3.2 are different part numbers; the lambda sensors are the same for both; however Police spec VX cats are a different part number again.
Forget Police spec cats as that is not what I am asking!!!!!
I am asking if anyone actually knows (rather than educated guesses, which I appreciate, but...not what I need to know) the actual difference between the VX 2.6 auto and 3.2 auto cats - not interested in the Police spec ones!!!!

Ring the factory and ask...
Might also help if you posted the respective part numbers, as you might find that there are actually six different numbers for the later dbw v6 ;)

Mr telemaker as you have both, types, off you go, it's all for research, and fair play. :)
I can't check as I have 3.0L plods on my 3.2 :o

Much as I'd love to, TVP fitted new cats to plod in 2007 iirc, and Elite has stainless sports cats ;D

O well, an ongoing quest.

I believe that at one time TVP had a little stock of genuine Cats and Exhausts....

It has genuine replacements on it, but your guess is as good as mine as to the part numbers ;D
-
Maybe the different part numbers are for downpipes with or without pre-cat codes :D

Today, I've spoken to the technical dept of both BM Cats and Euroflo and both state that the replacement cats they produce are of identical quality to OE parts, although this was the response I was expecting! Prior to the requirement for type approved cats, (required to be fitted from March 2001 vehicles) then the quality apparantly wasn't as good as OE parts. Their cats are the same for the 2.6 and the 3.2 (which doesn't really help with my original question in this topic). BM have a 2 year warranty, and Euroflo have a 3 year warranty.
I have spoken to Cats 2 U who state they are a supplier only and do not manufacture them. They supply BM cats for the Omega.
Anyone with experience of the quality of BM or Euroflo - is one better than the other from first hand experience, rather than mere opinion?

That's what I have (in type approved format) used on the 2.2's I've done. (From Cats 2 U) No problems to report.
