The cat on my Nissan QX is on its way out (had to have a new exhaust and what looked like a couple of ceramic beads fell out of the cat end) so, my question is - are there different qualities of cat, or is a cat a cat? Anyone bought from these people and are they OK? Feedback suggests that they are but a real-life recommendation would go a long way.

I suspect there are different qualities of everything. They're not over hard to change - silicone sealant, not exhaust paste, but TBH you can get them fitted for not a lot more money and it's a difficult job without a lift.
Yeah, you're right - not too hard to actually change but having a lift makes the job soooo much easier, which is why I'd get my mate to do it :o)
I'm just a bit wary about the price - £94 including delivery just seems too cheap. I paid £46 for a headlamp leveller switch (which consists of an LED, a fixed resistor, a variable resistor for the up/down adjustment and a bit of plastic - total cost at Maplins about £1.50 I reckon) for the Toyota Avensis!! And I remember the days when cats were many hundreds of squids. I just don't want it falling apart in two or three months, even if it is only £94.

you need to check/ask the seller whether it conforms to european legislation ie: its E marked & has type approval, should all be stamped on the housing of the cat.
I paid £110 for a Citroen Dispatch van cat fitted, to give you some idea...
John,
Have a look at this link

By 'eck, these things have certainly dropped in price since the early days of cats eh? :o)
Cheers mate, that works out even cheaper at under £70 including delivery - amazing :o)

Be careful, they DO vary in quality.
Garagiste mate is very wary of pattern cats, as he's had far too many which are a fraction of the size of OEM and only last a year or two.
Aha, I knew there had to be a catch somewhere :o(
I'll have to do some more research before buying I reckon. Cheers Adrian,

I always read that silicone sealant is bad for cats and that one shouldn't use it. My car passed it's MoT last year with the entire internals of the cat missing. I'm not sure how - Nationwide garage again.
Ordinary cats usually have a two year warranty and the better ones have three.
IIRC there was a poster from the manufacturer on the wall of the garage and it stated that you must use silicone and not exhaust paste - bits of exhaust paste can break off and damage the cat.
Maybe but it probably needs to be O2 sensor safe if it's used upstream of one.
I had a pattern cat on our last Previa and it outlasted the car. It was made in a small factory belonging to our local cheapo tyre/exhaust depot, B&M in Mansfield. £160 fitted on a Previa!
B&M make their own? I always assumed that place was a workshop and such things would be made in the far east...
Sheepbridge lane.
I know where you mean. Not far from the bridge they like to drive double deckers into. Just didn't realise they made their own cats.
Doki ("Doki" ) gurgled happily, sounding much like they were saying:
I'd be gobsmacked if they do anything more than weld flanges to pre- manufactured Cats. It just wouldn't be financially viable.
An old worn out cat can be worth more in scrap than the cost of a new cat, I guess the cheap new cats don't contain the precious metals that old cats do? We get from £30 to £100 for scrap cats.
Early Granada 24v exhaust system (inc cats) was around £1500 not so long ago..4 cats!!
