Decat Pipes

[Hostile Smoker]

I've been thinking of getting a decat pipe, do any of you guys have them?

There are some on eBay (Item number: 270319265671) sold by "2fast2cool2" who seems to make all sorts of stuff, is £90 reasonable and does the pipe itself look any good? Or are there cheaper / better alternatives?

TIA

Bear in mind that you'll need to swap your cat back in at MoT time.

Ah cool, that looks like a better option. Cheers! :)

What happens with the Lambda probes both sides of the cats? :)

Its different on the 300 mate,

on the 200 theres three sensors. the two in the manifold control timing etc, and the last one is just checking the cats working. i replaced it with an o2 simulator

Thank you for that! There seem to be 4 sensors on the manifold, 2 either side of the pre-cats and before the main cat. Where can I get an O2 simulator and where do I put it? ( no silly answers please !!! ) :)

[sparkystav]

an o2 simulator replicates the signal the sensor sends but thier pretty simple design and wont adjust as the engines running so you may need quite an advanced one.

But you wire them where ever you can fit them. I've wired mine to the wires right back in the ECU.

[lextech86]

do you need an 02 simulator on a 300 if replacing or getting rid of the main cat? i wouldnt of thought it was needed as there is no sensor after the cat

I would assume not then
