'75 Catalytic Convertor
Here in New York, I have to have a catalytic convertor, since the 1975 originally came with one. BUT, it doesn't have to work since I am exempt from smog testing. (yes, that only makes sense to the politicians)
Any recommendations on the least restrictive cat out there at a reasonable price? Has anyone ever opened one up to gut it, and then welded back together?
Any other ideas appreciated! Thanks!

If this helps any, I gutted the "pre-cats" on my 2002:

this way - it still passes the visual inspection.

I removed my stock cat and looked inside down the pipe. The element is very close to the opening of the inlet pipe, just take a long handled screw driver and have at it. You can get the insides out with no trouble. Then mount it back where you found it and when they look with the mirror it will pass...
