Hi just a quick question what would be better performance for my k10 a Performance catalytic converter or a straight through pipe without the cat?

decated, with a back box....and maybe another box, i.e silancer to give it abit more back presurre.. dependent if the back box doesnt give you engough back presure..

thats how i would have my system anyway
