I have a spare catted one which is partially blocked you can have.

I achieved a 20 bhp with a decatted Y piece.

Isn't your car a Pre-cat?

Hi, yes it is a pre-cat car but i have the later style exhaust manifolds with pre-cats removed and now just need to get the cat out of the y piece, or get a spare y piece with out a cat in it. Long story but i couldnt get the early style manifolds when i needed them, and i preferred the clip-on connectors. Either i need to replace the whole system back to original, (i know i shouldnt have strayed!!!) or get a de-catted later style y piece to get the car on the road for now.

I stupidly thought i could run a catted y piece with decatted manifolds but have now been advised that is not a good idea.

Haircutmike, when you say partially blocked, how does this work? You mean to get it cut out yes

I like this one, I think its a Clive Ford one? does he still make them?

Yep, cut and weld.

Peter, you have pm.

I cant really afford it right now but I do like the look of this though.....http://thumbsnap.com/f/Lw4FbK4s

Anyone fancy a griff number plate in part ex? K33GRF ?

Phil, I replied but you have autoreply!

You can have it for postage, ya have to help a grief guy out doncha !

[Alexdaredevilz]

Have fun

[my250gt]

Right, so thats what melts and blocks it up then. That has got to reduce the air flow big time.

Hoping to cut a square panel out the rear of it and get it out that way, rather than split in two. I think its possible to drill and gouge the pre cats out of the manifolds whilst in place, anyone done that, or can i leave them in? This will only be a temporary fix, would like to get a cliveF manifold on it long term i think.

[Alexdaredevilz]

Took me 6 hours with heavy duty tools to remove,

I will buy you a beer of you get it out with a square cut out!

You really need to cut it in two, but a few people have tried and failed with welding it back in the exact place

[my250gt]

Right, i love a challenge. didnt say how big the the square hole was going to be

[haircutmike]

Phil, got your mail, will post tomorrow.

[my250gt]

Peter, you're a star let me know cost. Cheers, phil.

[Geoff38]

will the metal re-cyclers still pay for the waste ?
And probably not a good idea to breathe in much of it when you are destroying it to get it out of the "small" hole.
Cheers G.

who on earth told you that you cannot run a catted y piece with the pre cats removed from the manifolds? removing the pre cats is one of the best things you can do on these cars, and you will still pass an MOT.

yes I still do the decat pipes, and have replied to your mail.

[my250gt]

Hi Clive, i have been told two different things. One, when i bought the manifolds, that they would be fine to use with or without the cats in, (so i put them on thinking i could remove the cats later on, or replace with a nice stainless steel one) and now that it is in for service and MoT i have been told that if i run it with the cat in the y piece, that it may over heat the cat as the resistor has not been changed and the mixture will be too rich for the cat.
Does that not sound correct?
Phil.

YES, forgot yours is a pe cat so yes it would cause problems, your best answer then is to fit a decatted y piece, you wouldn`t want ot spoil the fun by putting cats on a pre catted car anyway, if there is no legal requirement why bother

[my250gt]

Just need to raise enough funds for one of these beauties......

Have you heard a standard Y piece with the cat removed ? bloody awfull but you can weld a type of funnel on the inside to stop the awfull clatter noise.
