just had a quote from a place that makes exhausts to replace my centre box on my 4.6, they wanted £75 and thats in stainless. they bend it to the correct shape.

cant advise on de-cat though.

Thanks mate, doesn't sound like too pricey job then!

Can be done, not sure what the MoT would think of it though!

It is illegal not to have a cat fitted to any road going vehicle made in or after 1993 diesel or petrol. Construction and use regulations. However there is no check for diesel cats in MOT. Think i would wait until after January though, new stuff coming in again then i think.

i was close

i know the SRS is coming in next year, as in , warning light on dash constant = fail.

but got mine sorted today, some plonka had left it disconnected behind the glove box. connected it, ran the diagnostics, and all clear

Isn't it a diesel particulate filter rather than catalyst unit?

Also why do you want to remove it?

Hi

This will most likely cause a problem with the engine management system.

I know that the O2 sensors are monitored, so at the very least you will have O2 sensor errors in the system.

It's a diesel

Where abouts in the exhaust is the sensor? Its possible to buy a decat pipe so isn't it exactly the same if i just replace it myself? Sorry if my questions seem daft but im not very nolidgeable on mechanics (or spelling)

If it's diesel which it being a DSE is highly likely, it does not have a sensor.
