Decat or no decat?

[littleC18]

I have a 1.2 8v and i know most will be thinking....really. but i want my exhaust to sound more raspy and pop and bang a bit more.

I have a custom made cherry bomb style exhaust being put on on wednesday and was wondering if the decat would cuse any problems

ie...
limp mode
engine management lights
lumpy idle
loss in power
gain in power (<< haha i wish)

will it also use for fuel and if so, how much?

my first car had a cherry bomb on ( 1 litre uno ) and i loved it haha it was LOUD though...wait until you hear your new system and then decide on the decat

i have a powersprint gr.a on my ph1 172 complete system (63,5mm) with decat, and it's very loud+raspy!
I have just one pre-cat lambda so no managment light or whatsoever...so go for it.
