Re: Modifying the inlet/outlet of a cat
If you are going to tamper with it and remove the restriction here is an option.
If you want the visual effect of it still being on the truck just remove it and ream the guts out of it with a steel bar and a BFH
(sledge hammer). It is full of a honeycomb type screen element. Then reinstall the gutted cat
and you will have the visual effect.
