To de-cat or not to de-cat

[Brucesport]

Hi.

Thinking about de-catting my clio 197 leaving exhaust standard.

What do ppl think about this.

Any gains or not.

Thanks in advance

Less restrictive but a lot louder, so the negatives out way the gains in my opinion. Sports CAT all the way

Removing the secondary (main cat) & silencer is popular. They sound epic!!

You will notice the flat spot through the bottom end of the rev range a bit more though, some say it's worse than others.

I've got my silencer removed & have to say you only notice the flat spot if you're driving badly.


You can reduce the flat spot with a remap however.

I've not heard a standard 182, but I've got a decat and Ashley back box, it's very loud.. Tempted to put a cat back in or something.
