I have and '85 Nissan 720 4x4 King Cab, and I want to take the cat off. Where can I get the pipe for it?

nobody makes a test pipe for our trucks... you'll have to have one custom made

the problem with this is that most exhaust shops won't take a cat off and make one for you because its illegal.... you'll have to either find someone you know with welding tools, or maybe a performance shop

I'm pretty sure they don't make a test pipe fo the 720, but I'm sure you could fab something up or have a local shop do it for you. I had a new exhaust system put in and they cut off my cat, but they used all new piping from the manifold all the way back.

what about gutting the cat?

breadbox has a DIY somewhere for doing that.... i believe its in the tech section

Drop off the exhaust pipe and knock in a piece of rebar. Work it from side to side until the honeycomb is completely shattered. Start the engine before reconnecting the exhaust.
