Standard S2 or RS2 exhaust picture

I'm at work so can't do a fancy diagram. This family album shot shows what you can and can't get separate.

Here is one more picture: RS2 exaust

Thank you

My new cats turned up.
I'm impressed and not impressed all at the same time, but I can't complain as they aren't original.

Good points,
VERY small compared to OEM ABY cats, they are about the same size as OEM ADU (RS2) cats shown above by Rob and aRtiS.
Substantially lighter than OEM. Cheap, all in £173.47 to my door in one working day. Cat shell seams are plasma welded (that's some funky sh*t for cheap cats)

Bad points,
Mig welding isn't "brilliant", they've not had the gas up high enough (I could do better with an old arc welder), a bit spattery and a few porous parts to a few beads.
The brackets are Heath Robinson in the extreme

In real world terms compared to what dealers wanted (have they no shame?, just over £1000 for both? ) they aren't bad at all.

The catalyst inside is a ceramic honeycomb. I seem to remember the OEM ones are ceramic too, Steve? (Phatty) wasn't it you who found some chunks blocking your exhaust?

Both my original cats are dead, rattling like a french cars engine and most probably half blocking the exhaust. I doubt very much they'd get through the emissions test.

Going to remove the crap brackets, make up some better ones and tidy up the mig welds.
Ordered new sealing rings for all four ends, new bolts, new springs, new nuts and washers, plus all new fixings to hang them off the underside of the car.
Not flippin cheap for that lot either

Now I just know someone is itching to type I could have done this, that and the other, but I'm not up for all this 10" downpipe lark, chopping bits here and there etc etc etc.
I want to keep my original downpipe and in one piece. These cats will mate to my Milltek cat -back.
Ok, these might only last a couple of years, but it gives me time to find some "good" used OEM ABY or even better some OEM ADU cats in the meantime.
And no, I don't want decats either
Lets hope they fit ok----ish.

Where did you get them from? Plus what you doing with the old knackered ones? PM me cause i'll have the old as @ the right price............

[Jas11n]

www.buypartsby.co.uk is where they came from.

Shy bairns get nowt
I was going to bin them. Yours if you want them Lee, no use to me.

Hi Jase,

Yes it was my Cats that started to break up. It is indeed some kind of ceramic honeycomb that crumbles and cracks when old, including falling out and blocking one half of my exhaust!

Your new units look very similar to the one I have on my '80 Sport edition. They seem to be reasonable and it has now been on over a year with no problems...

Good luck.

Cheers,

Steve

Jase,

Just out of interest did you have to phone up and order them?, as i can't seem to find them on the website. Are the Part numbers 90603(LH) 90604(RH)?

I have a Milltek for the RS2 and my current exhaust is in bad shape so are the cats i may as well replace them whilst i'm fitting the Milltek.

Thanks
John

[Jas11n]

Yeah, that's them 90603 and 90604.
Hold on until next week, cars off to my local specialist to have these fitted. I'd hate for you to buy them and for me to come back next week saying they don't fit or were a huge PITA to fit.

Just had a look in the FA, the sealing rings are the same size between the ABY and ADU cats, which suggest they'd fit even though the RS2's pipework is slightly larger.
Must be said though, the pipework on these cats is the same as the ABY, so they could be a restriction in a way to an RS2??

Jase..

Jas11n,

As you said look good for the money.

@Steve, How did you realise one of the pipes was blocked, fall off in performance, sound, noise or was it only discovered when you were replacing them anyway?

Did bits of the cats "debris" come out of the tailpipes?

TIA.

Jase,

Thanks
John

Sorry John, forgot to answer that.
I bought them direct over that site and they were delivered by DHL in 24 hours.

One of my ceramic honeycomb cats broke up years ago, when I stuck a cold chisel through it.

[Smith_S2]

Thanks Jas i did find the numbers after all,, I'll keep a look out for your post on fitting the new ones, hope all goes well.

I wont be doing anything for another 3 weeks still got a bloody cast on

cheers
John

@Jamo - what loony tune cooked up an exhaust for you that omitted a basic essential support...

Had you not spotted that then you could be cracking manifolds and all sorts of pain further down the line.
