MG MGF Technical - Urgent: Anyone fitted a De-Cat pipe to a TF 135?

Anyone fitted a De-Cat pipe to a TF 135?
Some advice needed.

In the standard Cat there is a Sensor(o2/lamba?)
When you fit a De-Cat you fit a MIL Eliminator to stop the dash light coming on. My question is where does this sensor now go, when you use a De-Cat pipe?

I guess I would protect it (wrap with plastic) and attach it to something in the engine bay.
Where did you get you MIL from ?
Did you made it yourself ?

I have a de-cat pipe laying in my garage for years, but I first need to find an elbow to fit between it (MK1) and the back box.

Yup, tape it up and put it somewhere safe Gaz :o)

Fabrice, I got the MIL Eliminator from Brown and Gammons in the UK.

So when I fit the De-Cat Pipe I DO NOT need the sensor that I have fitted the MIL Eliminator to?

Indeed, I think you don't need the sensor (as a sensor), but you can't remove it from the circuit, so you have to attach it somewhere.

Maybe there are some de-cat pipes with a hole to fit the sensor back, but even in this case you would still need a MIL, because without cat, the oxygen readings won't please the ECU.

IIRC, a MIL was just something like a resistor and a capa in parallel wrapped in thermoretractable housing, or something like that.
It's an easy DIY job and worth 1 or 2 quid.

Thanks to Fabrice and Rob Bell.
All OK now.
Fitted De-Cat pipe and modified Sensor with MIL Eliminator.
Makes the XPower exhaust sound nice now.
Cheers.

Gaz,

Notice any performance increase?
Leigh

No power increases with cat bypass pipes - but usually a nice noise ;o)
