    Same as any exhaust blockage. Lack of power,not enough exhaust fumes coming from exhaust. If in doubt just cut the frigging thing out and put a piece of pipe in. Should only cost 50-100 to do.

    Should get a warning light in your dis.The you have to drive at about 40mph in third for a couple of miles to burn the carbon off the cat comb.It smells like bakelite.

    You must be thinking about a DPF not a cat. No wires connected to a cat and to burn soot out of a cat you drive fast.

    The standard cat is free flowing so makes very little difference to exhaust pressure/flow. Changing your back box will lower back pressure and make more difference to the turbo and power then removing the cat.
