Hi,
I'm planning on replacing my secondary cats, however I'm a little confused as to the layout.
I thought that the right section actually comes with three cats, one primary joining the manifold and two in the center, however I have seen some with just a longer pipe joining the manifold on the right and no primary cat then two in the middle such as this:
http://www.ebay.co.uk/itm/Mercedes-...arts_Vehicles_CarParts_SM&hash=item2ec33591ff
Can anyone tell me what the set up is on my car?
Also I don't want to open a can of worms, but I read some threads on here about actually removing the secondaries as they are not needed and were initially there for stricter regs in other areas of the EU.
I've also read a lot about 'blocked' cats and them damaging the engine, I've never heard of or seen a blocked cat, I've seen noisey ones but never any engine damage. What do people consider a 'blocked cat' surely if there was a problem with the capacity / flow of the cat it would throw an error.
Thanks,
