Just cut the Cats, they are just un needed weight anyways!!

Thanks for the input guys, I know that headers and high flow would be better but thats just not in the cards right now but I can always switch to that in the future. I love the sound of the spintech so I think Im going to try it. Pretty hard to make a chevy sound bad haha
