if you are looking to do this all you would need is a sharpened broom stick and punch through the first set of cats. The second set are resignators, and I dont think that they can be punched. I woulntd go any bigger then an inch when doing this.

I've been told to drive the car around and get the cats hot. Then, spray cold water through the tail pipes and the catalyst material will break up and spray out your exhaust. Don't know if it actually works or not. The right way would be to remove the cats and break the internals apart by hand with some sort of hard, sharp object.

Why? you won't gain anything . . . you have 2!! cats and a single exhaust. Your cats aren't interrupting flow, and even WITH the cats and dual exhaust, it's entirely possible to have TOO MUCH flow, and lose all your torque and low RPM hp.

The cats don't hinder performance on a stock cammed and headed engine.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.

They don't do anything to harm the performance of the car, there is a BIGGER danger in putting on duals that are larger than 2.25"

That will kill your performance, -the cats aren't a restriction, the danger is going too large on dual pipes.
