Looking for DIY Catalyic Converter Install

New to the forum, great resource. I've got a 2003 V6 double cab taco and need to replace the cat converters & O2 sensors. My skill level is DIY brakes, radiators, & all things fluid but have never done cat converters before. Would like to try it, any tips or links to DIY's for replacing the converters?

 

Rock Auto, welded flange cats is what I used.

 

Thanks, once the parts arrive does anybody know of a step-by-step DIY, pref with a few pictures for the newbie?

 

Haven't done it on my Tacoma but usually it's just un-bolt replace gasket bolt on new one pretty simple

 

It should all just bolt together.

 

Thanks, that's what I was hoping for. How about the O2 sensors?

 

if it is like mine was, you will need some pb blaster. i generally hit the bolts a few times at least the day before so it has time to work
