does a decat just work?



  K20 EG Hatch
put my standard exahaust on today and found out my original cat is fucked, cut and needs replacing :(
anyways what i was gonna do is just replace the cat with a yozzasport decat.
Will i just put in on and it works? Or do they have to be remaped or need anything else?
And it deffinately wont loose power.

(The decat will be my only engine mod).

Yep, you just put it on and it works, increases power a little.

An alternative, as your standard cat has gone, is to hollow out your cat, removing all the internals...

Will do basically the same job :)

Dan....it varies from car to car if your emissions light comes on...no problem with mine after 20k
 
  182 and 5 GTT
my emisions light came on after a few weeks with a sports cat so it will most probably come on with a decat. You might get lucky though!

A decat will go straight on but you have to bear in mind that it will probably fail an MOT with the decat so you will probably have to buy a CAT on at some point anyway.
