Is there any performance or computer related issues with gutting out the cat on a 1998 4.3 S10? I want to know if the truck will run the same (or better). I want to go with no cat into a 40 series flowmaster with dual swept side exit in front of the right rear wheel!!! Thanks:)

it would be better to get a hi-flow hi-po cat. no cat screws up your computer.
