Hello 

 

I have my exhaust off my car right now as I was supposed to fit a decat pipe, long story short it's incorrect 

 

I've read removing the precat gives good gains alone and is still legal in the U.K. To do

 

does anyone know if this will be sufficient enough to put a stage 2 super chips map on it?

Also considering smashing out the main cat depending on how hard it is

 

 

edit : thought against this
