Default Catalytic Converter Removal Question

I would like to remove my catalytic converter. I don't have any emission test requirements in my state.

Any thoughts on the best and easiest way to do it?

Does any sell a premade pipe with the flanges for a direct replacement?

Thank you

When i bought my car, the catalytic converter was already gone. in its place was a steel pipe. to me it looked like it was just cut out and the new pipe was welded on. i bet any muffler shop would do it for you cheap unless you can cut it out. the replacment pipe is the best looking area of my exhaust

the best place to get a "test pipe" is ebay. I got one for a '81 for about $50 w/shipping. it had everything needed for the swap.

if you have some sort of cutter like a sawzall you can just cut it out and autozone sells lenghts of pipe and just slip it in place put a u-bolt on each end tighten it down and your good to go, you can also like stated above just goto an exhaust shop and pay them to do it, shouldnt be too much. whatever you decide good luck.

I think the best way is to just take it off, remove the guts, and put it back on.

Cheap (free) and easy.

Not without violating a number of federal laws! No repair facility operated by a sane owner or manager will accept that work, no way. If caught, the penalties would effectively mean bankruptcy.
