Mk3 200 Exhaust Advice Needed.

[JWillis]

My mk3 clio 200 has a Scorpion cat-back exhaust, however I am getting an engine light for the post cat lambda sensor. I have bought a Bosch replacement althought the current sensor is fused into the cat and we are unable to remove, if we were to do so it would twist and possibly snap the housing on the cat.

Long story short, would my best option be to buy a Scorpion De-Cat to work around this issue? But then would I need it mapping? I am not quite sure how it works, hence the advice needed.

Thank you in advance for any replies

The best thing I did with my current 200 was put the original exhaust, cat and a new lambda sensor on! No more horrific flat spots, no more 5k cabin boom and no more EML light on.

I don’t have the original exhaust unfortunately...

I bought a complete 2nd hand one for £50 and sold the scorpion for £140.

have you tried heating the boss up?

No mate, basically took it to a garage, had a look at it and they said it would snap if they tried to get it out

Needs heating up with a set of bottles really. I'm certain it'll come out.
