catalytic converter bypass?

well i was thinking about getting cutouts but instead i want to pipe through my catalytic conv. were can i find a direct fit pipe 2 1/2 inch in/out 20 inch long. i really dont feel like cutting and welding for a simple project, or is it possible to take the packing out of the cats, they are both blow out and everything is ratling inside and i can shake it and the entire packing block shakes around so whoever installed them put shitty and cheap parts on

a long screwdriver and a hammer worked well for me

well using a screw driver, hammer, and marine corps issued 28in mashede i managed to get it all out now im wondering about all the shit that has blown back into the muffler and all the dust and shit that may have been going up through the headers in the past few weeks. but hey my power has improved alot. the block was entierly blocking flow and after 75mph i could not go now more without almost stalling out, now i hit 144mph no prob

mac and a few other companies sell off road pipes that bypass the cat. just hope you guys dont have emmissions controls in your area. i need them so i just bypass the cat and muffler
