to decat or not to decat

[RAVIHOTWOK]

as you will know from my previous threads, my car is going for a rolling road session and remap at hill power end of the month. At the mo it only has a cat back system and a piperx filter. Does any 1 know where i can get a det cat from and is it worth it? I have heard that they can make the car run worse due to the lamba sensors affecting the air/fuel mix??? Also my car is one of the 1st 172's, there seems to be 2 cats on it from the down pipes????? never seen this before. any sugestions????

cheers

get the decat before your rr session, then they'll be able to adjust the fueling.
IMO its worth it
