downpipe and decat quick question

[casper20v]

Just recivied my new 3" down pipe and de cat and my o2 spacer my question is I have two bolt holes for it to go on one on downpipe and one on decat witch one do I use?

You want to keep the first lambda sensor as it is so it will go on the second hole (decat section)

Awsome thanks berg

Have you bought the one off eBay £110 I think it is?
Any good?

Also you got a link to the spacer you used?

Cheers

Could you put the lambda in the decat pipe and use the first hole closest to the turbo for an afr guage

why is there two holes on the down pipe and decat , i have just bought the one off ebay , and now i see you need a space , i was hoping to fit on sunday ?

Not fitted it yet but looks good quality. And u need a spacer to stop engine managment light comin on. I just typed in lamba spacer on ebay and it came up 9quid included postage bargain!

Because our cars have pre and post lambda sensors

Wouldnt work as the pre-cat lambda needs to be in the first hole

You can use the hole for the second sensor (have second sensor mapped out) for afr gauge but it wouldnt be as accurate readings as its too far down the pipe.

Best bet would be to have an extra hole welded onto the pipe for afr/wideband gauge thats what i did

The eBay one sits on the bulk head and causes vibration

so , we have a pre and post sensor , why dont i just fit both back into place as it comes , wat do i do ??

You do, fit both sensors in the same place as your old pipe

But as there is no longer a cat in place the second sensor will throw up fault codes and engine management light so you buy the spacer to space it further away from exhaust gas to stop this happening.

i understand now , thank you very much

Sam is bang on with the eBay one banging on the bulkhead. I bought one and it had to be taken off. I'll probably be geting it modified though to fit. It's not just the bulkhead I had issues with though - I also had issues with it hitting on the bottom of the car. A piece welding in to bring the whole thing down should sort it.

hi this is downpipe from ebay?
get fitted without problem?

I've just put one of the decat pipes on from ebay, I can say that they are great quality but leave you with some issues. As mentioned a decat lambda extension will be required as my light came on after 10 miles of driving with the decat on..i've only just ordered it so i'll see what the outcome is.

However I have also got a EPC light on now and I have no idea what it is?

Can anyone suggest a fix or know what it is, sure it's been asked plenty on here. Thanks.
