When i was sold my car i was told it had a decat, this looks like the standard cat to me. Not sure if anyone can tell from the photos? May need to get the car on a ramp to inspect it further

If you didn't have a cat it would look like this

Because that is a dog, yes I'm bored to and from the outside it looks like a standard cat, remove the senso and have a look to see if its gutted but its not a "decat"

Lmao,

As above looks like standard cat, is it me though or does your gear box seem to have a lot of oily residue on it?

Thought that :/ ... It almost blends in with the shadow it's rather black... Maybe it's just wet?..

My gearbox is the same, pretty sure it's because my rocker cover seals leaks occasionally and it runs down the back of the engine and onto the box

That looks to be whats happening, is this an urgent issue?

On a side note: A gutted cat will actually decrease performance and a good cat like ones from Magnaflow will be nearly as good for power as having a tube as a cat, but without breaking the law.

Additionally, in the tests in the sources below, the straight tube lost a few hp an torque in low- and mid-range, which is in my personal opinion and in opinion of the tester bad for daily driving, because with lower power in low to mid range you will have to push the throttle a bit further there to achieve the same speed (imagine driving through a city or any limited street), thus needing a bit more fuel, which will add up over the years, depending on how much you drive.
