That's quite a Pelican ,Lizzie but at 200+ per cat I see how they got there .

I will fit it so just need a sensible price for the parts :)

But the way I calculate it is a write down, on a 5 year depreciation scale, of just 111.38 per year, which is in the acceptable zone for running a car ;)

If I were you I would consider taking the opportunity to source and fit a pair of 2.5/ 3.0 cats, which removes the issues associated with 2.6/ 3.2 cats. I would expect to pay around 120 for the pair.

That was my initial thought but curious where the 2nd lamba goes ( no rude comments please !!! ) and  is the wiring for the 1st lamba long enough ,assuming that the one that gets fitted

Yes, but I have to ask the question, if a pair of 2.5/ 3.0 cats do the same job why did Vx fit the 2.6 / 3.2 ones if it does not interfere with performance? ??? ???

They have an extra cat in the downpipe to bring the emissions back in line with the earlier higher compression engines.


I used THESE on my car for five years with no issues. Andrew would need another lambda boss welded on to use them on his car. That's another 10(absolute maximum) and a few minutes eay work to do as it's not on the car. Saves more than 100 per side. I would not pay 50 for 8 standard metric fasteners while there is still a hole in my arse!


I don't believe in using secondhand exhaust components(other than reliable manifolds), even if they are free.

As above really. The later ones are a bit of a bodge and don't work very well. Hence the emissions light coming on all the time.
I believe the old style cats were also better quality as they were always easy to sell for good money to scrappys etc.
The later have a lot less scrap or resale value.
As for the lamda question - It s so long since Ive seen the underneath of a 2.5/ 3.0 I cant remember how many lamdas they have.  :-[ ;D
It sounds like its only two instead of four though ?

So just to be crystal clear on this.

You can buy and fit std 2.5/3.0 cats as per Nicks post and images.You then get a friendly man with welding skills to cut and fit a second lamba boss into the new cat.

Fit the new cat and connect up to 2 existing lamba per side and jobs jobbed ...no lights or issues and only slight downside is the cats are as good as the OEM that are being replaced.

For 120 for 2 cats..bit of the welding and the bosses and good to go ...is that it in a nut shell then ?

Fancy an earner Nick ? :y

I'm with Nick, buy a pair of 3.0L downpipes, get a pair of bosses from eBay, get them welded in (there's a guide) cut 3mm off the new pipes, and fit, use some M12 nuts n spring washers,x4, drill out both flanges, exhaust end and fit m8x55, nuts bolts washers,  off you jolly we'll go.
