Freeze plugs are the stupidest thing ever invented

I was thinking so. But not totally sure

Like your project my wife sees me drag stuff in my shop with the Bobcat the junk yard won't take for Scrap Metal. The Mercedes had not been on the road for over 2 years, I gave the kid $1800 for it.

Oh what a travesty. Some poor person takes the trouble to crawl under your vehicle and cut the cat of. Just to find out someone has removed all the precious metals.

One question I have never seen a satisfactory answer on is why when all engines are manufactured Brass Expansion Plugs are not installed at that time. If you buy a Marine GM engine it has brass or at least they use to.

They don't want them to last forever

On my 1990 Geo Tracker I removed the cat completely. The will cause problems down the road.

When I went to germany back in the day, American vehicles with catalytic converters on them, had them removed and a plain piece of pipe installed in it's place. Regular fuel only. If upon your return and you shipped your vehicle back, it was replaced.
